So with a little research I think this is what happens. TM is based on a scale of 1000 and you have to reach 1000 to take a turn.. You start with TM equal to your speed, so BB8 starts with 280. He gets 16% of 1000, so his TM at start of battle is 280 + 160 = 440. Revan starts at 320. That's the end of the first "turn." Since no one reached 1000, everyone adds their speed to their TM. So BB8 is now at 440 + 280 = 720. Revan is at 320 + 320 = 640. No one reached 1000, go again. BB8 is now at 720 + 280 = 1000, Revan is at 640 + 320 = 960. BB8 goes first.
Now, assuming this is correct, what happens if neither gets to 1000 that last time. Say BB8 is at 995 and Revan is at 960. Next TM add puts them both over 1000, is that where RNG comes in to determine who goes first? Or do you have BB8 at 995 + 280 = 1275 and Revan at 960 + 320 = 1280 so Revan goes first?
