Re: NEW: OPR Android App
 
Thanks for the app update. One suggestion I would make, though, for the next update would be to add a function to update all the regionals at once. Because how it is setup now, is that you have to go into each separate regional and update it one by one.

There is no refresh all button... this would cause the app to try and calculate all oprs for every team at every regional and I felt that the processing power would be too much on the phones.

That ought to be more than enough to process every match at every event, if you use the right matrix factoring algorithm.

Sorry, I probably should have specified. I meant for everything except OPR. Like team lists, match schedules, results, etc.

Sorry for all of the late updates, but OPR FIRST 1.2 is now available. Another update may be up shortly but I wanted to get another update out to make the app work. Look for it to become available on your phones shortly

But OPRs and scouting reports are always useful, if only for entertainment's sake!

Jason
Older versions of OPRNet had a "self-check" mode for their predictor - if a regional was complete when someone asked for a prediction, it would tell you how good the predictions would have been if it had made them with the data available after each match. So it would say:
"After match 59, the predictions for matches 60-80 would have been 65% correct"
"After match 60, the predictions for matches 61-80 would have been 64% correct" (it varied a lot)

Generally what I found was that on friday night, saturday predictions based on the sum of OPRs for each alliance were 60-70% correct, which is obviously way better than a coin toss. This depends on the game though - OPR is better or worse depending on what the game is like. See the 1-hour mark of Karthik's presentation at champs last year for more details.

Post-event (aka once you know all the data) it was 80ish% correct, but that's a fairly worthless stat: once the event is over, anyone can get 100% of predictions correct!

Am I the only one finding that this app straight up doesn't work? I couldn't pull anything for BAE all day, while FRC Spyder was working fine.

Re: NEW: OPR Android App
 
I'm not getting anything from the 'Team Statistics' choice for the Kettering University District event and even though they and BAE's Granite State Regional have played the same number of matches so far (52 through Friday night), BAE does give me OPR rankings. I also don't get any data for the other District event this week (Traverse City) even though I currently get OPR data for every Regional that played matches today.

Is there an issue with the way the districts are set up, either in the code or real life, that's causing this?

You beat me to it :D I was just typing this up when you replied. Check for an update within the hour. Here is what I was typing though:

OPR FIRST 1.3 is now available. Plenty of bugs were fixed today - so I apologize for all of the inconvenience. Nice thing is, I believe I updated all of my bugs and it should work fairly well now. If I notice any others, I will update them as soon as possible. The revision from 1.2 to 1.3 fixed:
- Now can display match stats from District events (Ie Kettering and Traverse City). The district system made parsing different but I fixed it.
- The awards page didnt work but now does

Now on to functionality! Should be coming up shortly (the new cool functions :D) but give me some time on that. Thanks!

Thanks for the update, I didn't actually get 1.2 until about 2 hours ago so I wasn't sure what the issue was. I guess I'll be waiting until morning for the 1.3 update though. Google Play doesn't show it for me on my computer or my phone yet. Thanks for the update ^_^

I had to go back an inspect the match schedule to verify, but we were partnered with 67 and 11 in a match each, and never faced them in quals. I swear we had the luckiest match schedule of the field. Ended up seeding 2nd after HOT had a freak loss towards the end of quals. 111 picked 67 and went all the way, IIRC.

OPR data after an event is certainly useful.
Yes, i remember that match they lost. We were their partner.
