It's funny how waiting a week (and being american helps) and using a poll can change as what things come across. My thread really made me look like a dick.
The poll is a nice idea.
Some questions about your questions and some suggestions for your options:
"How many rounds would be played per segment?" - There might be a bit to few options for some weird things like 5 minute segments with winlimit 1.
"How would wins-losses be scored?" - option 3 "Each Round Win scores as One Point" do you mean league points?
"If there is a tie, how would it be handled?" - There is no option for golden cap per map, per segment doesn't reall mean the same thing (think about 2 maps, 2 segments each).
Also I need a checklist for mainclass, I've never decided for one.
Imho time per map and segments per map depend on the number of maps per match. I don't mind halves but I want every match to last about 1 hour* (that seems to be the worldwide consensus anyway) and I think halftime breaks after less than 20 minutes are pointless so I'd rather not have halftimes if more than one map is played per match.
Maps per match is influenced again by maps per week and matches per week, of which the first one is basically personal preference and the latter being determined by weeks per season and maps played per season. The general consensus here seems to be ~8 weeks and 14-16 maps played which results in 2 maps played per week.
That means that in the end it comes down to how many maps you want to play per week.
One map per week: Play the same map twice. If you don't want to play the same map twice in one match and still want 1 hour matches you have to play two matches per week and 1 hour per map.
Two maps per week: Either play two 30 minute maps in one match or two 1 hour maps in two matches.
I haven't really done this before but I imagine only practising one map per week to be very boring, so I think 2 maps per week are better. However I can't decide whether I prefer one map with halftimes or two maps without halftimes per match. I don't know either how hard it is to schedule two matches per week instead of one, but that is probably heavily team-dependant. From a spectator point of view I'd say two maps (1 map might get boring/cut short), but as a player I don't know how to weigh the more difficult scheduling against the haltftime strategy talks.
tl;dr
Can't really decide between 2*30 mins per map or 2*30 min maps per match.
Pretty sure about 20-30 mins per "segment" (be it map or half), 1 hour per match and 2 maps per week though.
*That doesn't really apply if you play more than two maps per match. On a sidenote: Never play gravelpit for a lot more than half an hour. If it's not over by then it's just a giant stalemate. I really like gravelpit and I can even deal with half an hour of stalemates but any longer than that and it just feel horrible. The worst what could happen in a gravelpit match was: 15 minute round, switch sides, repeat. Repeat again. You've just spend one hour playing gravelpit (+30 minutes for the second/first map). Oh it's a tie? Enjoy the bo3 adding another 30 minutes of gravelpit. omfg, it was hell on earth.
