So, a thing I started doing basically for me, to have reason to keep improving. Its just a spreadsheet, made in Open Office Calc, but should work in any Excel, there are no macros, just formulas.
It has a list of tracks for each car, and benchmarks for each track. You run a time against the benchmark, write it in 00:00,000 format in the green square, and you get alot of statistics and graphs. If you don't have time on a track, it just adds 10 seconds to the benchmark.
So far I have benchmarks for F3, FVee, SuperV8, Superkart, Formula Retro, Formula Reiza, Formula Classic, Formula V-12, Formula Extreme and the Mini. Didn't have time to test how good most of them are yet, but the F3 ones seems to be spot on - quite challenging, but achievable.
I pretty much needed something like the site GPLRank... that thing pretty much singlehandedly learned me how to drive decently fast.
Anyway, you can download it if it looks like fun... Ill add the other cars later on.
In the zip there is ods file for open office and xls file for Excel.
