Questions about “boosted” pancake swap farms

I’ve been providing liquidity to 2 pairs for a little over a year now. Every month or 2 I go in and collect cake from my 2 farms (harvest all) and then lock up the cake in the syrup pool.

About a week ago I notice one of my farms has a yield boost available. I did the necessary clicks (2 transactions), and now that specific farm is “boosted”.

1) what does “boosted” even mean?
2) how come I can pay another transaction and boost it again? (By only 1.009x)
3) how come when I log on, it only asks me to harvest from 1 farm instead of 2 now?

It honestly feels like I’m getting cake slower now. Wtf did I do?! 😂
