Hi, I checked your Pine on the blockchain. It has 100 paid waterings, and 6 of them were bonuses, not 2:

#15 Aug 6, +0.180
#17 Aug 8, +0.180
#28 Aug 19, +0.180
#54 Sep 14, +0.216
#59 Sep 19, +0.216
#75 Oct 6, +0.216
Each one is a transfer from @hive-grove with "BONUS!" in the memo, so you can see them all in your wallet history.

6 in 100 is below the average of 10, but it isn't rare: about 1 in 8 Pines ends up with 6 or fewer after 100 waterings. Across all players, Pines got a bonus on 10.35% of 15,186 waterings since September, in line with the 10% shown. Every watering is a fresh 10% roll and past results don't affect it, so your next waterings have the same odds.
