New versus Old focusing method

Unsure if you mean 3 lowest points - but that was not the case. The line intersection was never far from the low point of the graph. For the times noted in my text, if you had the time , you could probably check back on the numbers....but never mind for now. This weekend I will be taking down my gear before heading off on a short trip. When I come back, I want to do some maintenance on my set up before imaging again. If I run into this again in the future, I will for sure get some AF packs to show what I am experiencing. Until I actually sat watching this in the early hours this morning - I have not noticed this setting the focus point so far away from the bottom of the curve before.....it had me very confused re WHY! I think we must be getting some bad electricity here in SE Spain just now Image may be NSFW.
