The compression tests

This morning parts of open waters were frozen over! Winter is coming!

I went to my Mustang to finish the remaining 7 compression tests. It went well and I didn't run into any serious issues.

These are the results. The small number is pressure in bar, the high number in psi.

I'm not sure what to think of these numbers. 9.5 and 7.8 are a little too far apart for my liking. Now what?
