It seems to me that all 16 entrants are given ample time to complete Round 1. Great.
However, the quarterfinalists are sometimes only given 15 minutes to play their next round once the Round 1 clock expires. This is absurd! This leads to a series of withdrawn players that ends up making what should be a tournament with 15 individual match-ups into a bunch of walkovers. This seems to ring true for free CTTH and 9-hole tournaments.
I also am a firm believer that winners of a tournament should receive more rewards than what they currently do.
