Mediabase question

[bamafan2102]

What is the cutoff time on Mediabase that R&R uses to compile their Top 30 for the week. It's interesting to watch the charts and see how they change daily.

[drock89]

The cutoff is on Sunday. They do 4 updates : 3am, 11am, 5pm, 9pm, all PST. At the 9pm they send the songs recurrent for the week, and normally the spins/audience jumps come in at the 3am and 5pm updates. This is the only day with 4 updates, every other day updates at 3am and 11am.

[bamafan2102]

Thanks you very much. I never knew what the cutoff was so this will be helpful.

9 PM (PST) on Saturday is the cutoff point for the following week's issue of R&R.

You mean Sunday ;)

BB's monitoring period is Monday thru Sunday; R&Rs is Sunday thru Saturday.

Then why does Mediabase do all its big updates on Sunday?

[Marv]

Because their reporting period ends at midnite (EST) on Saturdays.

If you look at the bottom of every current-based chart in any issue of R&R, you'll notice that the notation states that their charts are based on Mediabase's monitoring for the period which ends on the previous Saturday.

Mediabase crunches the data every Sunday, and those are the numbers they turn in to R&R.

Trying to follow this carefully and not sure how I'm doing... do me a favor, Marv, and tell me if I understand this correctly. This is what I believe to be true:

Regardless of when the data are obtained, the numbers POSTED on the MB site at about 6pm Pacific time on Sunday are what appear in the next week's R&R, with only one adjustment: the songs that go recurrent are removed later on Sunday night.

It doesn't matter to me if the cutoff is Saturday night or Sunday morning; what I'm trying to understand is when the R&R final data can be seen POSTED on the website.

Thanks in advance.

Mediabase is a day late. So technically it closes on Saturday because Sunday's numbers aren't calculated. Otherwise you got it right.

[bamafan2102]

Now I am really confused. I clicked on the Mediabase chart on another thread and got a completely different chart even though it says it was updated at the same time as the one I am looking at. For instance Phil Vassar is at #10 on one and 14 on the other. The one that I have a link for also still has Jo Dee at number one while the other one has Gretchen. Which one is right and where does that link come from? The spins are way higher as are the audience impressions. I a guessing it is a total of all stations, not just country but if that is so, why does that not count in the main chart when compiling the show?

Here's my guess what you were seeing...

The Mediabase mmr247.com website has two different country radio panels it keeps track of. For links with a format=C1R in it, the R stands for the R&R country panel. Links containing format=C1M are for the larger Mediabase country panel.

Ah hah! Thanks for clearing it up, Perp.

I'll have a definite answer for everyone on Wednesday evening, since R&Rs new charts are posted to their website every Wednesday @ 3 PM PDT.

I've been tracking the performance of a certain song's Mediabase performance for historical reasons.

What that song does on R&Rs new chart will allow me to answer this question regarding Mediabase's cutoff period once and for all, so I'll stand by my previous answer for now.

[Matt4319]

We've known this for like 3 years now. The R&R tracking period runs Sunday-Saturday. Mediabase updates the data for a particular day the next day, meaning the numbers you see at 6pm Pacific on Sunday night on the Mediabase website are the spin totals from the previous Sunday through Saturday (i.e., the tracking period for R&R). Marv is saying the same thing everyone else is, but unfortunately has confused a number of people.

[Marv]

As usual Matt is correct, and I'm sorry if I confused anybody, but he and I have been saying the same thing. The Mediabse update which usually gets posted around 9 PM (PST) on Saturday is what R&R uses for their charts.

I was hoping that Tim McGraw's 'Drugs or Jesus' could somehow crawl up to #10 despite losing 400 spins, and a song or two ahead of him going recurrent this week.

My 'historical reason' from my previous post would be that he hasn't missed the top ten with any single since 'It's Your Love' wound up #1 for the year, but now he finally has.

Okay Tim, now it's time to start a new streak!!!!

What you see on the 9pm Sunday update is what is reflected on R&R for that week. I'm not taking about when the reporting week ends. I'm simply stating if you want a snapshot of the week's R&R numbers, you have from about 9pm Sunday night to about 3am Monday morning (Pacific times) to get it. If you look at the publicly available Mediabase site anytime outside of that 6 hour window, you won't have the accurate R&R chart for the week.

You can't wait and wakeup Monday morning after that 3am pacific cut-off, login to Mediabase, and use that as the week's R&R. It's not so bad for us here on the west coast, but I'd be ticked off on the east coast, since I'd have to capture the Mediabase chart in a window from midnight to 6am... and I'm NOT a morning person! I don't subscribe to the site, so I only have access to whatever the public sees. If you subscribe, do they keep a static copy of the full R&R chart for that week around?

[drock89]

You can kind of get an idea though. You take toll on the songs without a bullet. Then see what's left when you wake up. You also have to be focusing on one song and see which the songs are behind/in front of it to see if it was passed/passed additional songs.

[Perp]

Yes, you're correct that if you take the 6pm Sunday evening results, and then manually drop the recurrents from it later on, you'll have an accurate R&R chart for the week. That does give you a bigger window. I don't recall ever noticing changes in spins or audience between the 6pm and 9pm Sunday night updates. As far as I know, the only difference has been songs being dropped on the later update.

Normally the only spin/audience changes happen at the 3am and 6pm updates. Although during the week, the 12pm update may update with 3-8 spins and 1-3k listeners being added, sometimes more and sometimes less.

[Marv]

Perpetual Emotion--Are you saying that the Mediabase update which comes @ 9 PM on SUNDAY (PDT) includes all the spinsd their monitoring system has detected as of 9 PM (PDT) on SATURDAY?

Since they do post an update @ 9 PM (PDT) on Saturday, does that update includes the last song that all of their 2,166 monitored stations played on Saturday evening, before the stroke of midnight, in their respective time zones?

[drock89]

They don't post a 9PM update on Saturday... ???

I have to agree. I save the Top 50 songs of the Mediabase / R&R chart each day, using the last update for the day if possible. Here are the previous 17 Saturday upate times I've saved...

I don't recall seeing a 9pm Saturday update before. I wonder if i've been missing them all this time, somehow?

Sorry, I don't know anything about what specific times a chart week's monitoring period begins and ends. I just know that the Sunday, 9pm PST update matches exactly what R&R posts to the public on their website the following Wednesay as THE official, weekly R&R chart.

[drock89]

Have you noticed the afternoon updates aren't coming..yesterday there was none and today is late.
