Did not get any silver this time but got some deep clad again.
Okay Bill, I've watched a few of your F5 video's and found them to be very well done!

A couple of things I noticed,
One you have tabs notches out, yes, and I know why. But For the past year or more I've been playing with nickels and in that I'm finding that with most of the detectors I have tested them with Nickels come up scale the deeper they are in the ground, tabs will do this also. Now, I'm pretty certain that the only nickels your notching out is shallow ones, nickels @ the 8" range may come in as high as screw caps or zinc pennies, I'm thinking the 5" to 6" may be in the upper tab range. (if the F5 does the same thing with nickels as my detectors do)
It would be interesting to see if you could find what target range those deeper nickels are falling in? (I have an Omega and Nickels go up scale on it the deeper they get)
And here is something else to help you,
Those beaver tail tabs (beer and pop) were put into use in 1965 and was not replaced with the square tabs until 1975. (Hint) if your finding those tabs in the 8" range then that dates that layer to be in the 1965 to 1975 range. So, your just barely making the silver age. In your video you stated that the older stuff may be out of your reach, conclusion! you're probably right.
I can't see the whole area but I'm thinking if the area has any high ground, or slopes that if you hunt those you may find things a little bit more shallow, which may get you a little bit more silver. Low lands will often times collect more soil growth, the hills or slopes has more run off which can reduce soil growth.
I would love to hunt that area your hunting in the video, all the deep clad means that there should be a lot of good finds there. The problem for me might be the same as you, having a detector that will run that deep and cherry pick the good stuff.
