Basically, I think you're proposing to spend a tactically relevant amount of time (enough time for Yammar to lock on and fire or tsew up to and brutally maul one person with half his power level) divided up into two weaker saiyans, within the area Yammar can reach. This worries me.
Well, the idea is that Yammar can't reach us. IT no-sells the fact that he's twice to three times as fast as us.
Slightly modified proposal. Making an effort to be more clear.
[ ] Plan: Shell Game
-[ ] Take another bean. Suppress Ki levels. IT to Dandeer before Yammar realizes you're up again. IT with Dandeer to the opposite side of the earth. IT around the world in a random pattern.
-- [ ] IF: Yammar has not caught up to us after an IT or two, AND we sense him trying to chase us THEN: multiform into 3. All 3 continue suppression of KI levels.
-- [ ] Kakra 1 continues to IT around the planet while in possession of Dandeer. Kakra 2 ITs to Jaffur. Kakra 3 ITs to Apra. Kakra 2 and 3 grab Jaffur and Apra and IT away.
-- [ ] Kakra 1 continues to IT around while in possession of Dandeer. Kakra 2 and 3 feed Jaffur and Apra our remaining two Senzu beans.
Or some variation thereof. Even assuming Yammar can get close enough to hurt any
one Kakra before they IT away, there is practically no chance he'll get to all 3 before they manage to feed either Apra or Jaffur a Senzu Bean (or both). The Sealing (chapter title "Prelude")
decisively demonstrates that IT spam allows weaker Super Sayains, and indeed even
non-Super Sayain sayains the ability to effectively play keep away from full power Super Sayians. The only reason Berra ever managed to catch up with us during the Sealing (while we were
vip-ing around with Jaffur) was because: A) we stopped to talk to Raditz and B) Jaffur charged him like a moron rather than staying put and letting Kakra IT them both away again.
