Ninja is generally harder to speed tune, especially with an ally attack champion like Fahrakin in the team, because his A1 increases his own turn meter. Point for Geomancer.

Here is a great guide how to speed tune a team. https://deadwoodjedi.com/speed-tunes/basic/

According to that, I think your Fahrakin should be a bit faster, as he is going after the UNM boss right now. If the whole team shall go before the boss, the speed should be between 191 and 209.

You made a typo at Jareg's speed, but I guess it's 204. If 24 stands for 240, he would be to fast and put your team out of the turn order.

You did not add Vogoth's speed. I think for him, it doesn't matter if he goes before or after the boss, so a speed between 171 and 209 is good enough.

P.S. I would not start the fight on auto, do the first round manually. Geomancer's passive only works, if the burn debuff is from his own skill. If Geomancer fails to land the debuff in his first turn, Fahrakin may land his burn. As that one would get extended by Vizier, Geo could not land his own burn debuff anymore in the whole fight.

So start manually, if Geo lands his burn, you can turn on auto. If the CB resists, Fahrakin is not allowed to use his burning/poison skill until Geo's cooldown is over, you would have to do the first rounds manually in this case.
