Greetings!:
I like to know the ways of doing a list with the top 100 best times in a race using blueprints!? :S
Thanks in advance!!! 
Make struct that holds best time and player name (maybe more).
Make array of that structs size of 100.
Fill that array with some long times (or something easy to beat up, or progressive from very easy to very fast lap times).
At end of race, search array from longest time to shortest.
If your lap time is shorter that one you found, shift (move) all results below it down by 1, and insert new time in freed spot.
