340 Static Compression Numbers and Test Procedure

Hi, I just did a static compression test for helping sort out a bunch of other things. So I just would like to focus this thread on static compression testing procedure (not sure if I did it correctly) and to share my numbers because they were higher than I anticipated and not sure what it means. So any comments on the numbers also would be appreciated.

Procedure: All plugs in and measured cold cranked until no changes seen typically 3-4,5 times
Motor:1973 340stock steel heads high rise Mopar Manifold Holley 650 double pumper lots of unknowns CR? CAM? Pistons? Deck height etc?
Data
Cy/PSI
1 210
8 202
4 204
3 210
6 207
5 215
7 197
2 197

All readings are within 10% of the minimum and maximum range.
I assume the numbers would rise if done on a warm motor right? How do these numbers relate to the compression ratio?
Thanks in advance for the reply......
