Pato's fixed bearing tool still in error?

As many of you will know, there is and has always been some issue with bearing tools and the nav map. Pato's tool, although being a must-have to many, me included, also suffered from it. One of the old MaGui mods I still had on my HDD had a fixed image which I installed on the new WS MaGui installment of SH3/GWX3.

To my surprise it was still 0.5 degrees off:
I had map contacts enabled and had the sound guy track a target. Tracking lines moving clockwise, he would not report the new bearing until the tracking line hit the degree marks spot on BUT

This has always, to my knowledge been a real issue, that there is a consistent rounding error in SH3 that has nothing to do with any plotting tool.
Set the depth to 25 meters and the boat will most likely stop at 24.5 m. Come up from below and the boat will level at 25.5m.
Turn clockwise to 90*. The boat will stop turning at 89.5*. Counter clockwise the boat will stop turning at 90.5*. To get to 90* dead on I need to fiddle with the rudder manually to set the heading.

I assume therefor that the sound guy is guilty of the same, rounding off reporting 105* when the tracking crosses nearest half.

Therefor I assume that Pato's bearing tool would be correct if the tracking line was at nearest half when the sound guy reports the new bearing, NOT right on the degree mark.

EDIT: Just to clarify. I know the worst was that the old graphical error was inconsistent so that eastwards had greater error than west but this I just saw here with Pato's being consistenly 0.5 off all the way reall caught me off guard.

Can someone chime in here and fill me in on how this is supposed to work now after these fixes of Pato's and probably other fixes as well.

No wonder my 4 point bearing showed USS Enterprise at low altitude full throttle. Off 0.5 degrees when the sound guy already has given me a full degree possible error really add up to bizarre results.
