I asked in the range office and the guy said he didn’t know and I should try downloading a manual. Great. Anyway I looked at the manual on the website (and google) but can’t find anything that tells me what is what (apart from the obvious. )
Can anyone with some knowledge help me out please? I have attached one of the cards.

I’m guessing the x-mid and y-mid is the average hit point. I assume total is the total point along with the first value after the 1,2,3,4etc on the breakdown (however why do some have V and other don’t?)
Also the values next to them, I know it’s how far off from centre, but is that in mm or some other denomination?
Also does anyone know the dimensions of those targets on electronic century and the dimensions of each ring? Can’t find that anywhere either.
Thank you. Steve.
