Event contest unfair to higher level players

It seems to me these events are unfair to those of us playing at higher levels. I remember when I was in the levels below 1000 if I got unlimited lives for say 30 minutes, I could get on a roll and rack up a bunch of levels and even earn more unlimited lives. But now that i'm in the 2300s i'm lucky to complete one or two levels. So how can I compete with players that have much easier levels?
