Engine & spark plug Condition info, FYI

Here is just some data for your interest. I replaced plugs and then pulled them after about 1 hr of total running time over several weeks. While I was doing that I checked the compression as well, both dry and with a few squirts of oil in the cylinder.
There isn't necessarily a question here, but I thought y'all would be interested in the results. Your comments are always useful to me. Overall, compression is low and most cylinders do not see a significant increase in compression with oil. This makes me deduce that it could use a valve job more than a engine/piston ring rebuild although I don't have any short term plans for either.
In this pic, the first # is compression 'dry' and the second is compression with oil squirted in.
Note. It isn't on this pic but cyl #8 is 100/105
