Compression sounds fine. Smoke could be oil control rings leaking slightly. If it's only after sitting and on cold start it's probably nothing for immediate concern. Just make regular oil changes.

pretty sure you want to do a compression test on a warm engine.

compression test will read lower on a warmed up engine and that's the reading you are interested in.

also, that's not much driving for that period. potentially, the oil control seals may need a bit of run time before they loosen up, pop out of the rotor and do their job. oh, and agree on oil change suggestion above, you may also try 20W-50 (assuming you're using 15W-50, now).
