You can see the pictures in the other thread taken from pilos seat in real 109 and HTC 109. The view should be slightly wider even from 0 deg angle, and if you lean forward the effect is stronger.
Eg. the windshield in P51 is made very well and its chamfered armour glass is made very well to represent the RL affect of armoured glass. It should be done to 109, too, although its armour glass is not chamfered the same way, so it does not have quite as much benefit of the optical features of thich glass as P51.
Actually the present model looks as if there was no armoured glass at all and the outer part of windshield framing obstructs the view which it does not do in case of actual armour glass.
I was lucky to find a piece of 55mm thick perspex glass and experiment how much effect the glass actually has. IIRC at 45 degrees view to glass the 90 deg cut side should be optically about 27,5mm wide but it actualy looks only 18mm wide and that is the widest view at the side! So you actually CAN look behind a corner with thick armour glass.

"Im pretty sure HT is open to hard facts and backed up data."
Of course. I wouldn't imagine they would discard any data presented to them in form of actual pictures of actual a/c in question.
Edit. "You'd really have to lean your head way forward and either side to take an advantage of refraction."
No you don't. It works right from 0 deg up to 180 deg -if you can put your eye that close to the glass...
