The Heading Bug is a Degree Out

[Jazz]

Since I received my Bravo throttle quadrant the other day I have been using the knob on it to adjust my heading bug and course needle on the HSI and therefore have not just looked at the pop-up tool tip numbers and have been looking at the gauge itself and it has become obvious and very annoying to realise that the heading bug is not in sync with the numbers that display in the tip box. Neither does it align with the needle when you set the same course on both. The heading bug seems to display 1 degree left of what it's actually set to. The visual depiction of the heading bug is always 1 degree left of what it should be.

This is the kind of niggle that drives me nuts.
