Yes, the screenshot is a bit rough but it was taken at a low resolution which could explain that.

My script translates H4A5 to 0.4.3 which I believe is correct as other segments are working using this formula:

x.y.z where:

x = a/b/bs/c: 0/1/2/3
y = segment 1-16: 0-15
z = H1-H4: 0-3

I'll investigate this a bit more but would be happy if you would like to take a look.
