Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
With v6, I was not able to get predictions for the Los Angeles regional (CA). Am I doing something wrong, or did is something on FIRST's side screwy?

Edit: v7 now up. The only external improvement (I think) is that predictions are fixed and now work mid-way through a regional. Edit2: Fixed a parsing issue with single-digit teams. |

I m looking into giving it a run offline option (-o) in case there is no internet publically available at the Philly regional. I am thinking about saving all the html results files in a local directory structure (instead of the temp file). That way on Sat I can update the html file by hand and keep re running the calc. I am not sure if I will have time to get this working or not Thanks, Brian |

Usage: cmd line: perl scouteval.pl {qualmatch}.txt ---- which will create a file called results.txt, and where {qualmatch} is the file created from the usfirst match results page, copied into a text file. Then use whatever software you use to solve the matrix for the team OPR+ and DPR+ values. The OPR+ and DPR+ values (sorted by OPR+), as calculated for the DC regional, is as follows: Code:
Team Number OPR+ DPR+We are working to automate the process. Let me know what you think! Steve |

I get this error when I run Oprnet on some regionals. (BAE for one) I know Peachtree and SanDiego work, but haven't found others that do yet.

The format for a line will be something like REG_CODE,MATCH_NUM,RED_1,RED_2,RED_3,BLUE_1,BLUE_2 ,BLUE_3,R_SCORE,B_SCORE Where REG_CODE is the usfirst.org regional code. There will be 1 line for every match at every regional (roughly 48*76 = 3648 lines). Once the matches are verified I'm also going to put in a new 'feature' that writes the parsed lines directly into the Java source code for the next time the code is compiled (which is often for me since I use a similar program to do my Fantasy FIRST picks). The order it will check for valid data is source code --> local parsed file --> local html file --> usfirst.org --> tba.net ... and it will go until it finds valid data. Buckeye data still isn't up though, so I wonder what we'll have to do to get those scores :confused: Then, eventually I'll put a scouting layer on top of that so you can input data into it at a regional. Then, I'll make a simple version of this input, so someone can input it via PDA, iPhone, or whatever other touchpad technology comes available. This part won't happen publicly till the offseason though. I've been away from it for a few days since I was at the FL regional, but now it's back to work to have it done in time for Atlanta. -- edit -- Ooh and a w00t to Greg Marra and crew for simplifying the tba.net urls for each regional and year! |

I ran through all the regionals that worked (three didn't) and put each one on a spreadsheet. I also combined tham all into one sheet (master). hope this is useful to teams.

The fact that my former team, 116 is ranked 3rd at the event should be the first indicator (as well as the ranks of 45, 365, and 234 being so low), despite struggling to score the entire regional. I don't have the raw OPR numbers handy (on my Mac), so I can't give detailed comparisons between the rankings, but judging by these, I think it may have become less accurate to what the team's real performance was. |

During DC, I had my scouts do extensive scouting on each match, looking at how many MRs each scored, and how many MRs were scored on them (developing a match by match +/-). What I failed to do, was to have them track the HP and how many SCs the team delivered to the HP, both of which had profound impact on the game. If I just looked at the performance of each robot, 45, 365, and 234 were on the top of my list. But I knew from observations that 2199's HP was deadly, and 118 had the ability to get at least 2 SCs exchanged. So I wonder if there isn't some aspect of the OPR+ calculation relying on those other factors, and not just how effective the robot is. I'm going to run these numbers (looking at all three factors - robot, HP and SCs) while we are in the midst of the competition at Chesapeake this weekend to see if I see any trends. Perhaps this equation isn't going to give us the info we are looking for, but I still want to run some additional numbers to see how they do. Best regards, Steve |

It was perfect because we were #1 after Friday. And therefore it must have been the best tool ever. Just Kidding, however, it really did help in our meeting. It confirmed that KRUNCH was as amazing as we thought.

I pulled the data from FL, and ran the calculation for the finals, using the OPR+ and DPR+ numbers. Here are the results ... First, averaging the score across all three finals matches, the avg Red score was 74 and the avg Blue score was 84. I plugged the calculated values into the OPR+ and DPR+ formulas, and here is the outcome Red 68, Blue 90. An 8% difference for Red and a 7% difference for Blue between the predicted values and actual values. Penalties, which are not considered in the calculations, could easily account for that kind of discrepancy. In doing so, one thing became obvious, the OPR+ number can not be taken into consideration by itself, but must be linked with the DPR+ number - but not simply by adding them together - but in the separate calculations of Red vs Blue Score. I'm going to do some additional modelling of the data to see how we can get a combined ranking value. I am going to run additional calculations at other regionals and see how they correspond. Steve |

Hi, I've been trying to access the ratings for the Dallas regional, and the program has not been able to parse the html data. Does anyone know why?
