Thank you all for response. I understand that you need more data if you want to be accurate but If a multiplayer replay plays fine for me then it should be also enough data for me to analyze, especially if you are a noob and have +3s lap times. I would just like to get general look on where/what I should improve. It would be nice to just pick any lap from any previous race and drop it in the analyzer but I understand that is not possible... :|

lfsworld.net/rafa is not working if I open a link but it works if I click a hotlap analyzer icon in https://www.lfsworld.net/
Also this is done in flash so you need to enable it it a browser. Some browser don't support flash anymore.

A few gigs of replays is not a big concern but I thought maybe there is some other reason it's not recommended for auto-record, like more lag or something...

Hi, I've just see you got this awesome analyzer but I can't figure out how to use it to analyze my own laps.
I understand that you should upload some hotlap in hotlaps>hotlap charts>choose file and upload but I see that records are not saved in spr format. The only spr I have is that downloaded form "Online racer stats" best lap but it's not accepted because I didn't have the account name in game. How I can see any of my lap in hotlap analyzer?
Also why there are different formats for single and multiplayer? How they differ and why the game don't recommend to save online replays automatically? Those mprs look nicer - file sizes are smaller and rewinding works almost instantly which is not the case in spr where slow rewinding makes it practically useless...

Thank you for any help
