I myself am math challenged
Get away with ya!
If you are Math (Maths in the UK please
) challenged then I am Henry the VIII.
Of with ya head!
I have to say though, that for anyone who wants proper Pico support, where you can find the answer to all of your scoping questions, then Tom at Autonerdz is the way.
Best to buy the tool from Tom & gain the benefits of "Full Access", rather than pay annually for it.
For the serious scopist, it really is a no brainer.
I look back & realise that this is the way I should have gone.
