Tyrant -> Sweetwater?

I revisited SweetWater vs Tyrant and i have a few different things to conclude.
Firstly, calculating the +30% boss vs Stats and Atk depend on each individual character, but possibly can be generalized.
Secondly, Each star enhance will transpose onto SW. So, it is a personal preference of when to stop enhancing, NOT a number of stars that are better or worse. You only lose the the ability to add more stars, if you are below max (15).
Thirdly, SW set bonus must make up the difference in tyrant base stats for any/every comparison, not the number of stars.

Sws Cape vs Tyrant Cape Base Stats Comparison (one piece)

 Spoiler

Clean Tyrant Stats +50 Atk +30

Clean SW Stats +12

Transpose Stats -83 Atk -30

SW 3rd pc bonus Stats +75 Atk +35

If you only have a SINGLE tyrant to transpose, AND, it makes your 3rd or 4th set bonus, your range will increase irregardless of stars.

Sws Cape&Boot vs Tyrant Cape&Boot Base Stats Comparison (two pieces)

 Spoiler

Clean Tyrants Stats +100 Atk +60

Clean SWs Stats +24

Transpose Stats -76 Atk -60

2pc set bonus Stats +25 Atk+20

3pc set bonus Stats +75 Atk +35 (2+3) Stats+100 Atk+55

4pc set bonus Stats +95 Atk +48 (3+4) Stats+170 Atk+83

If you are transposing TWO tyrants that make your 3rd or 4th set bonus, your range will increase irregardless of stars.

When the above statements are not true, transposing over tyrants will lower your range.

Every version of transposed tyrant, will be greater than tyrant alone, when scrolled.
