If you got a 25L pw wash to 10% then there's only a possible total of 2.5L yes? So that's everything including fores, heads, hearts and tails. Less 150-200mls of fores that's 2.3L assuming you can extract every drop (which is unlikely to have a wash after a run with zero alcohol left)
So work for around 1.75 - 2L tops. If you were happy to keep all 2L of 95% neutral I think you'd be doing better than most off a 10% abv 25L wash. I rarely keep a full 2L out of a refluxed TPW. But I tend to be ruthless with heads and tails. Keep less, run more often.
