Should the G250V adjusted correctly VFF with the crescent either facing diaphragm or mouthpiece?^---- THIS!

I really want to know what's going on.
Like I said I built 30-40 of these and never encountered this issue.
Tested today... Crescent facing diaphragm free flows, crescent facing shank no free flow. Two different G250V though.Politely disagree, @couv. What you say sounds logical, in terms of "catching the airflow". But for some reason (case design?), it works the other way around. I don't think the manual is mistaken.
In any case, I think Scubapro got out of the habit of teaching max performance, and into "least complaints from occasional divers" regarding freeflow. At a SP seminar three years ago, I'm sad to say that the instructor was completely unaware of the capability of reversing the vane to increase performance. Had to show him that page from the manual.
Can someone with a G250V that freeflows without the mouthpiece compare the two vane positions?

Exactly. Which I think is why they prescribe the "rental" position by default in the recent manuals.But if the best performance (highest VIVA) is when the crescent is toward the aspirator then would that not cause more complaints?
