Lets say I have a level 9 Legedary "Paitient Zero"(PZ). In order for me to get them to level 10 I need...

(1 x Level 9 PZ) + (1 x Level 1) = Level 10 PZ

From that point I can proceed to level him up to 19 normally. Is this correct? Following that, does the next evolution go like this...

(1 x Level 19 PZ) + (1 x Level 1 PZ) = Level 20 PZ?

Or like this...

(1 x Level 19 PZ) + (1 x Level 10 PZ) = Level 20 PZ?

I'm hoping its the first because then it would take 6 PZ total to get to level 50 whereas the latter would take (i think if my math is right) 55 total PZ's to get to level 50.

Now here's where I have some questions. Does level of unit not make a difference?

for example...

(1 x Level 9 PZ) + (1 x Level 9 PZ) = Level 10 PZ ???

Or Does it take total exp earned between the two units and make it level to that?

For example...

(1 x Level 9 PZ) + (1 x Level 9 PZ) = Level 13 PZ ???

Can anyone further clarify and explain anything else I might have missed?
