In the past, races in scotch have been to 4 on the winners side and 3 on losers side. Trying to understand the changes this year: First round is almost all race to 3 ?? - with just one or two matches in each bracket listed as a race to 4??- then the rest of the winners side is listed as races to 4. Losers side is still all a race to 3. Do not understand why the first round is almost all - but not all cases shortened to a race to 3. We came all the way to Vegas to only race to 3 in the first round? IMO - race is too short as a true test on winners side. Can anyone explain this?
