Wash, rinse, repeat!
The fact that it got better indicates that something is afoot. I
don't see how it could be anything but rings, _unless_ it's inside
the injection pump. (Which gets engine oil for lube, but that does
zero to explain a compression problem.)
I don't see how dead-dead-dead rings could get better at all from
running on thin juice, so the fact that it's changing at all is
encouraging.
In order for rings to seat, they MUST be free to move. It's the
combustion pressure that seats the rings, but ONLY if they are free to
move outward within the groove when combustion pressure occurs. Carbon
deposits CAN immobilize the rings. Conceivably the flush loosened them
sufficiently and now they are sticking again. If that's the case, then
the engine needs to be run at high speeds and load (makes the most
possible heat) to burn out the carbon. The use of Mobil 1 (or some other
group IV/V oil) WILL greatly facilitate this as such an oil will free up
carbon almost as well as the flush (and will be a lot safer).
