Instance Preview – Static or Variable Algorithm

Since I’ve found out that the static fonts use a different interpolation algorithm from VF ttfs, I’ve wondered what the instance preview window at the bottom is then – is it like the static fonts or VF?

[Edit] From my own test, it looks like the instance window is showing sometimes what matches the VF instances, other times what matches the static instance…

The instances in the preview are always the static instances as there is no algorithm for VF interpolation, yet.
