Why is there a 4 day break between Upper final and lower round 3
Presumably to do with weekend spike in viewership. Also player strain - teams from groups, Zeta/NIP for example already have to play 3-4 days in a row to get deep in playoffs.
Also don't think it has anything to do with Easter, since the break is Tues-Thurs, Easter weekend is sort of Friday-Monday which is the first half of the playoff bracket.
