What Phil said. Compression gauges are really only useful as a comparator, if all cylinders are the same, then all is going well. The best way to judge how well the compression rings have bedded in is to look at the blow-by coming out the tappet cover.

As soon as I get plates on the car I will go ahead and break in the rings (8 to 10 times going 30-50-30 mph on the throttle right?).

Yeah, that's good. Modern rings are pretty good out of the packet, the moly ones are pre-lapped & don't need any real bedding in at all. The bores might glaze up before you get your plates, but it's no big deal as it will come good with a bit of full throttle work in third or top gear.
