Tub Caulking Pin Holes

Over the weekend, I removed the old caulking around the tub and replaced it. Being a pretty straight forward task, and not being my first time, it should have been easy and pretty flawless.
Somehow I ended up with small pin holes in the calking.

The steps taken was as follows;
- Remove old calking (knife and paint scraper)
- Clean area with alcohol wipes.
- Use hair dryer to dry area
- Run bead of Mono kitchen and bath caulking
- Smooth in/press in with finger
- Allow to dry for 24 hours

When I checked on the job ~12 hours after the fact, there was half a dozen small pin holes in the caulking in a various areas around the tub. Oddly enough, most where in areas that required ~1/4" bead were other areas that required very little where fine.
This has never happen to me before. The only thing I can think of that was different this time was the really low humidity.

Any ideas as to why or how this could have happen?

Not sure about the why, but are the pin holes deep? or just on the surface?
I'd probably just smear a little bit of caulk over the holes. The biggest concern is the bond between the tile and tub. If there aren't any cracks on either side - it should be fine.

The holes looked to be through the caulking. The caulking was used to seal between the tub and the plastic surround.
I added more and pressed it in lightly, filling the holes. No issues after the fact.

I've never seen this before, so I was just wondering if there was something I didn't know.
