I do not have the means to run the numbers, but I did see life open up with 16 hatch (after double extractor trick) into 15 ov, 15 pool.
After attempting this opening on ladder, I have come to prefer it, especially in ZvT and Zvz. This varient has a few advantages
16 hatch 15ov 15 pool
Pro:
- Much faster Hatchery: Since Hatches give more supply than in Hots this allows you to skimp on 3rd overlord until after queen and ling production
- Faster Pool: This allows you to get faster queens and lings with a few advantages
- TvZ: Queens out faster to help deal with reaper, lings ready for it
- ZvT: Makes you immune to virtually all ling rushes, IMO this is the biggest benefit to this build
- TvZ: Queens out faster to help deal with reaper, lings ready for it
Con:
- Less early Drones: might negatively affect economy (more below)
- No Hatch pool Hatch: Due to earlier hatch and pool timings, you can't afford a 3rd hatch before pool finishes
While the lack of hatch pool hatch is obviously a big deal in zvt and zvp (at least in some maps), the only other possible problem, less drones, may not actually matter. If someone could empirically test this it would be great, but theoretically there are two reasons why I don't think this method is overall less economic than 13 ov 17 hatch
1. Full saturation is 16 drones in LOTV, as opposed to 24 in HOTS/WOL, so the early extra drones you delay are the least efficient drones in your line(14 15 16 if you don't gas before pool). Meanwhile, you actually get drones 14 and 15 quicker at first because of the double extractor trick
2. Faster queens = Faster injects = more drones
3. 3rd Overlord delayed, allowing those 100 mins to be spent on drones/queens beforehand.
Am I missing something or is this the better opening in most situations?
