it's gone. I haven't seen it for over a year.

I didn't realize that it's been that long. I thought that I used it last season. Dang, I'm getting old.....

I noticed on the new an unimproved MRN web site that they no longer have YTD driver ratings - at least, not that I could find. Track-by-track driver ratings, but nothing for the year, and that big PDF full of stats like fastest on restarts, fastest late in a run, etc. seems to be gone as well.

Makes no sense to me why when other sports start to embrace analytics NASCAR can't even tell you who's quickest for two laps after a restart anymore.

It was a pretty valuable tool to see who did what over a race.

Absolutely.

One reason I love Indycar's lap chart and full-race section time data. You can make full race length time charts.

I'll bite; what do you do with them?

I'll take a guess, playing the Vegas odds?

I use a few of Racing Reference's historic driver performance data (average finish at a track, DNFs, Top 10s) for picking my fantasy team. I don't know what I'd do with numbers like 'Fastest for three laps after a stage caution on concrete tracks in the second half of the season'. I guess I'm not particularly stat oriented.

Is there a reason to not publish them? Maybe you don't like to, but plenty of people would like to be able to do a data dump and do various analyses. Seen it plenty of times with the huge Alkamel timing databases WEC and IMSA put out. Maybe NASCAR thinks us fans are just too dumb to grasp anything beyond how many Top 10s a guy has.

Well, someone has to accumulate them and format them for publication. Maybe the sites that were doing it weren't getting enough hits to make it worth even that minimal, automate-able effort.

It's not a question of my not liking to. It's more like it's something that hadn't occurred to me, and I'm trying to understand it.

Toss up a link to the databases you mentioned. It might be that taking a look at them will enlighten me.

The lap by lap info should be super simple to obtain and post. Nascar keeps a record of every car's positions on every lap. Racing-reference has the loop data, which to me would be more complicated than having the simpler lap to lap data. Doesn't make any sense.

makes sense, they have made it impossible to ask them where the hell the lap by lap data went.

Yep, if you click on certain stats links on Nascar.com you'll be connected to Racing-Reference.

Huh. Right down there at the bottom.

If you want YTD driver ratings, I can start posting them each week. Last year, I copied the Loop Data from every race since its inception in 2005 into a single spreadsheet. I can now create pivot tables for any stat for a specific year, driver, track, track type, etc..

I just wish there was an efficient way of copying/pasting to the forum. Going thru a service like photobucket is time-consuming. I guess I could tweet LoopData stats and then embed them. I dunno. I used #LoopData to tweet out a couple charts last year.

According to NASCAR the only questions we should be asking are: Is Dale Jr. done go run good this week? Yes/No, Is it time to start thinking about Jardiance? Yes/Yes.

Sorry, this is from a week ago.

You can map an entire race in a spreadsheet and chart it. Oval races due to having so many laps it's just a ton of data. It's good for the Lights and other races, you can view real-time driver performance taking into account items like who got stuck behind what car since that's not always a driver's fault. Also becomes easier to spot who hides behind wave arounds and other gimmicks to stay close to the leader. I'll see if I could put up a couple pictures of what I'm talking about.
