So far our score in PBP knowledge:

I wouldn't say that, and you might not if you saw what my code looks like when only written for myself!

I'll end up using it because that part of the program can be slow, so I'd rather it tight.
Just had to remember to fill up the array with an acceptable value at initialisation so the low voltage cutout
doesn't kick in straight away (values start out all zeros), so I initially fill the array with the first stable voltage reading.
