I am lost, here are my results.
First I am using a spot meter as I do not have a densitometer and I do not have a lab in the area that I woudl use one so I am trying to figure it out with a spot.
The FILM is ACROS 100;
I think the film speed is 80 though but I do not really know what to do as I think the dev time is too short for zone VIII
Light Box f11.3-4
Blank Frame f8.07
2/3 difference gives a density of .2 each 1/3 in fstop = .1 in density change according to the directions on this site;

But I am just so confused.
Here are my reading for each neg for Zone 1 & Zone VIII targets
Frame1 f8.0.5
Frame2 f8.0.6
***Frame3 f8.0.3 Zone 1 target
Frame4 f8.0.0
Frame5 f2.8.0
Frame6 f2.8.3
***Frame7 f2.0.6-7 Zone 8 target
Frame8 f2.0.4
So a .1 difference from blank frame would be frame 3, 1/3 stop.
The matching frame then would be frame 7 which is 4 stops.
Am I good or do I need to add more time to development? Or am I doing this completely wrong??
Thanks,
Kev
