Meh, haha, I'm not going to replay this level, I got 3 stars on it using the boost at the end (extra bubbles for 9 gems) so I'm done with it. Onto the next island!
(Although, for the record, I've done what you're describing too.)
Ultimately I'm sure it's *possible* to beat with 41 or 43 bubbles or whatever, but I'm pretty good at this game -- maybe not as good as you guys, but still -- if I'm struggling, I'm pretty sure other players are as well.
