So , if you trim 'UP', the effect of the elevator in the extreme upwards position would be slightly reduced.

Aha, so it does influence throw.

As for the game-in my experience trimming does reduce the maximum throw of a control, even if that should not be so

Btw: not all planes had trim ruders, the 109/190 had some sheet metal which bent on the ground afaik.

It is more or less opposite in IL2, where trimming the elevator DOWN, for example, reduces the effectiveness of the upwards elevator, unless you pull it to the really extreme position- and nobody ever does that actually.

I'll have to check that, but...
As much as I hate to say it, I think you got a valid(your only one imho) point there.
It would also explain why using trim in IL2 reduces your turn radius.
(hear say - if it really does, that should be on the top of fixes)
