from start to finish the event has over 60 days (closer to 70) total average about 5 medals a day and you will complete it with extra time.

course that is the base statement some days you could get lucky and get 5-6 in an hour and some times 0-2 i know when i was doing the grind i could go 20 fates without a medal and sometimes get 4 medals in a row rng is pretty mean but that's how it is.

the only real advice here is the sooner you start the slower you can take it.
