Clan Boss speed tune help

Okay, I waited a long time to get a good (or some good) protectors for Clan Boss. I finally got some good ones, but I cannot seem to get the speed tune to work right. I'm using dead wood's Clan Boss calculator, and (assuming the calculator is accurate) I cannot seem to get the math to work out.

The team: Skullcrusher, Morag, Jareg, Trumboar, Ninja.

I have 3 protectors there, my plan was to have a different protector go right before the clan boss each time he goes and do a protect. Skullcrusher's has 3 turn cool down, so I was going to run him at 1:1, but Trumboar and Jareg are both 4 turn so run them at 4:3. I reason that so long as each protector is tuned to go right before the boss, it won't matter where everyone else is in the rotation because obviously they won't get 2 full turns and lose the protect buff. But no matter what speed I seem to give my 4:3 champs, they can't keep a consistent order (and somewhere between turn 10 and turn 15 Trumbor and Jareg stop protecting at the time I want them to). I did the math and if CB is 100, 253.3333 should be the correct speed, and I figured 254 would be close enough to not make a difference within 50 turns.

If I have to, I could swap someone out for Duedan the Runic, he has buff extension. But he also has to 4:3 because it's on 4 turn CD. And who do I swap him in for? Jareg is my -50% atk person, Trumbor does leech which is most of my healing, Morag does strengthen and I have her built as my secondary damage, Skullcrusher counterattack is valuable, and Ninja is most of my damage. I also have Hotatsu or Rector Drath that I've considered throwing in.

I know I'm not going to 1 key UNM, but I'm hoping to at least 3 key it and 1 key NM. Preferably 2 key it.
