This is a pointless exercise.
Check out "binomial distribution".
Without hundreds of germination reports of ceeds from a particular breeder's strain, any information you get on gender ratios here won't be statistically significant or meaningful. You're never going to get that data.
Might as well try to deduce the "fairness" of a coin by looking at ten flips.
Instead, you're just going to get a small number of individual reports, potentially biased by people who were disappointed in their gender ratios. People remember packs with 8 males/2 females a lot more than they remember 3 males/7 females!
Put differently, assuming 50-50 gender ratios, and normal 10-packs of ceeds, you should expect full 1 in 6 packs to give you 7 males OR MORE.
Even though that's totally NORMAL, try telling that to the poor sucker who draws a pack with 8 males and 2 females!
And even if you did manage to somehow get data on hundreds of ceeds of a given strain (which you won't), at best that data would only apply to a given lot of ceeds. Since most breeders create new ceeds every year or two, any data you collect will likely be obsolete by the time you collect it. And since most breeders don't label their runs with lot numbers (or even if they did, most growers are noting them), there is no way for you to know which lot any given report is from, and therefore no accurate way for you to pool/compare the data.
Germination rate data is probably a lot more useful, just in knowing which strains might fall short, but that still leaves a few potential problems. Some growers simply don't use the best proper technique to germinate ceeds, and that could be an issue in reporting. Some growers don't store ceeds optimally, again potentially affecting germination rates. Some ceeds may be old stock that have sat on a shelf for quite a long time before the ceedbank sold them or mishandled by the seedbank. If so, that's not necessarily the breeders' fault if ceeds don't germinate.
So if a grower says (for example) that only 7 or 10 of his "fruity-kush" germinated, you don't know if that's because the grower didn't do a good job germinating them, because there were issues with storage somewhere along the line, or if they're just old. You also don't know if the problem was isolated to a particular batch of ceeds, and may have been fixed by the breeder already.
