Fantastic tool!

But I do feel that something about it is a bit off, everytime I run the script i feel  like it keeps setting the voltage lower and lower.

I ran the script 7 times in a row without doing any changes what so ever in between and this is the results (I converted the hex into decimal too to make it easier so see for us that are not used to hex values )

Is this normal or am I doing something wrong?
