Actually low compression can be intermittent. If it's a gap in the cylinder rings rather than something related to the valves it's possible that oil is filling the gap and allowing good enough compression for it to run reasonably well.
That being said, I'm with tjmr2 in suggesting that you consider doing a leakdown test.
If you don't want to bother with making your own tester EMSPowered has 'em too.
