Oh no! My boosting group fell below ideal numbers, but we still have enough to start the match! Whatever shall we do?
To piggy back on these existing solutions, I thought I'd mention a few things that my boosting group figured out along the way. Credit here goes to TilltheMorning and WC Aries, who were the first ones to tell me of these little tricks.
Once your boosting group falls below about 8 people, you'll notice a significant decrease in the number of points you'll get in a match. If you get as low as 4 boosters, you'll be getting a paltry 270 points per 15 minutes, if you are switching at the 7:50 mark. And that magical "150 hours" target that people often mention when they ask how long this will take? That requires you to get somewhere around 318+ points per match. This just won't do. So, there are two solutions to this:
First: TilltheMorning's Overcapping Technique, as handed down to him by those mystical German boosters we heard of but never saw. This works best if you have no more than 8 people, though perhaps 6 works best. Here, the NEUTRALIZING TEAM goes beyond neutral (blue circle) and HALF-CAPS the control point. That means that the capturing team MUST let them capture 2-3 of the 5 segments of the circle before stepping in, neutralizing the half, and capturing it all the way. (Hear that, capturing team? You gotta LET them overcap. Don't be too jumpy.) Using this technique, instead of getting 6 points per capture, you get 9 points per capture (the neutralizing team gets nothing extra, but that's why we switch the roles, don't we?) If you are using this technique with 4 people, that pathetic 270 points per match shoots up into a much more respectable 320+. If you are doing this with 6 people, it gets as high as 340-360.
This doesn't work as well with more than 6-8 people because the overcapping is so fast that they can accidentally end the match. All it takes is one or two people out of sync or for Alma to send a lag-spike your way and everything ends. I suspect that this overcapping thing is part of the reason why matches with 12+ people net you so many points -- the neutralizing is so fast that overcapping is unavoidable, so you end up getting more points per capture (7-9) even if you are trying your best to jump in right at the neutral point.
The second technique, brought to us by WC Aries, can be combined with overcapping for maximum results. It has been mentioned already above, but I'm not quite sure how you would get it to work with 8 people. We found it best if you have 4 boosters total. This is the Same Teams, No Switching technique. If you can orchestrate the lobbies in such a way that the teams are always the same, every single match (by policing joining order, though that doesn't always work out and you'll do a bit of backing out and re-joining), then you can go the full 15 minutes without switching. This does save the time at the switch point, and with 4 people you will get approximately 340 points per match (~600 in one, ~100 in the next).
To keep it fair, though, you really have to put in the effort to make sure the teams are always the same, and we found a little bit of randomness in which team you get thrown on when you join larger lobbies which would make this difficult with more than 4 people. I suppose it can be done, but who wants 15 minutes of lobby-engineering before you can even get one match completed? Leave that to the double-boxers.
So don't fret, my puppies! Don't let those 4-person, 270-point matches get you down! And boost until you lose too many people to even start the match!
NOW GET THAT ENTIRE AREA NAILED DOWN, PRONTO!
