As pointed out below, 2 single runs against a target dummy are not a substantial contribution to theorycraft. At the very least you need to include your logs so that they can be broken down and studied, we aren't just going to take your final dps results at face value.
I did 2 different DPS cycles test currently on the raiding dummy (self-buffed) and in my current gear set (Armory):
1. TPx3 > RSK > FOF > BOK (with cooldowns), I came to ~54k DPS. I also kept up the TP buff.
2. TPx3 > RSK > BOK, also keeping up the TP buff came to be ~60-61k DPS.
I dunno, it just doesn't seem ideal to use FOF at all, especially in situations where you can't really be steady for too long or if something happens and you have to cut it short...kind of a waste of chi tbh. Theoretically it could prove to be ideal to have it in there but the advantage over using 2 BOK in it's place is so very slight I don't think it will honestly matter.
