Misunderstanding Boosting

[Ualaa]

The goal of new 5-box teams on KJ.
Combined with four throw away accounts.
And wanting all of the granted levels to go to A.
Kind of has me stumped.

Maybe its 5 existing accounts + 4 throw away accounts.

In which case we go with one booster.
And then up to four more accounts in the party.
But the best we can do will be two existing accounts and two RAF.
So:

Booster
Existing1 -- RAF1
Existing2 -- RAF2

Pretty sure this is what you have listed, in your post.
Let's say Moorea does to 2 sets to 60th.
And then grants a 3rd 60th on Existing1 and Existing2.

It will be cheaper/longer, to repeat the process with Existing3, Existing4, RAF3 and RAF4.
The faster/more expensive option will be character account transfers.
Without transfers of some sort, whichever account boosts has only one toon.

Well it's kind of like this

A-B
B-C
C-D
EFG
ellemeno-p

where P is the antiderivative of X,
and also a^2 + b^2 = c^2

a + b + c = x. iI x is less than the cost of a RAF, we don't do one.
