because the other day i was playing gt3 and i was at 68.sumthing% and i was annoyed i was so low in percent because i had completed all beginner and arcade and rally mode. so i finished the single player races in arcade and when i had only gotten to grand valley speedway reverse(about half way?)the game said i had achieved 75% and awarded me the 787b. i then finished the rest of the races and checked my percentage and was delighted to find that i had just over 79%.
but yeah... i never realised how long this game takes, im at about 90% right now... i just bought two new games though so i wont be playin gt3 for a while.
Maybe that 2% was talking about the Time Trials, not the actual Arcade Races...cause i think the time trials only give .2% for each completion (and there are ten...)
i'm fairly sure that once you get to 99% there are no more tenths of a percent... i was kinda worried because i had 99% and had a few time trials left, beat one, and it stayed at 99%
