Stripping runs at Woodford Distillery

[der wo]

I am researching about stripping runs. Woodford is the only famous bourbon brand, which works with potstills. So their numbers are more interesting for us than the numbers of continous distillation distilleries.
Here is a short video:

Unfortunately there is no info about the abv of the mash, but:
-after 1. dist. they get 40pr
-after 2. dist. they get 110pr
-after 3. dist. they get 158pr

Unfortunately there is no info about diluting between the distillations. But it sounds as they don't dilute.
Do they really strip down from let say 16pr to 40pr? So per 100gal mash they collect 100 x 16 : 40 = 40gal low wines? That is 40%. We normally strip only max. 25%.
And from 40gal 40pr, they collect 40 x 40 : 110 = 14.5gal high wines?
And now they have 14.5 110pr in the last still and collect 14.5 x 110 : 158 = 10.1gal (minus fores and heads of course). So only 14.5 - 10.1 = 4.4gal remain in the still?

I am thinking about my next grain project (rye) and thinking about getting more (good) taste without going deeper into the (bad) tails while the spirit run. If longer stripping is the answer. And find more and more data (similar numbers also from scottish malt distilleries), that I am on the right way perhaps. I am also working on a rummager for my still, that I can strip deep and on the grain without scorching.
