Regarding all the math from a few pages back... I think these are the relevant post (thank you Len):
Lens counting at HM they counted 1,750 people enter the LL in an hour, they also know that ~300 of those are G+ so but this count ~82% of the LL for HM was DAS, Golden Oak, or Rider Swap.
Apparently Len has gotten some confirmation that his numbers are close if not a little low.
Finally official word from Disney... but it's all outdated that GAC was 3.3% of people, but could take up to 30% of TSMM capacity. Also DAS has Tripled in the past 5 years (which I can't find the number but I think Len said this was also low.
So if we combine this data. 3.3%*3= 9.9% minimum now probably have DAS. Also they are taking ~80% of the HM LL in any given hour. I think these are probably conservative numbers to use when trying to look at the effect these DAS changes will have on the Standby and or LL queues.
What I can't see much evidence on (and would be very helpful for our hypotheticals) is average Standby vs LL ratio and the average party size at WDW.
@lentesta any help on those 2 numbers?
