I believe you to be correct on all points. I personally think 8 is to low and specific delete would be great as I like to have each cars best lap not 8 of the same single car. But that's just me hence wanting specific delete also.Funny enough, GT3 could hold around 15 lap times (if memory serves me), and you could choose to delete specific results.
The game should record all lap times, allow players to delete individual times as well as search times for a specific make, model, PP range, etc, and implement online time/drift trial leaderboards for every layout of every track, with the option to search specific players, specific cars, PP range, download another player's ghost, and so forth.
I agree 100%. I only do Time Trials and Seasonal Events nowadays and to have even 25 spots would be great.This is currently my biggest pet peeve. I'm done with career mode so time trials are about all I can/want to do. In this case "Eight isn't Enough".
