Alright my people, I did a few test and this is what I get. I didn't test it against all characters as the first time because the % repeats.
Olimar 0%, Town and the City and only using the Blue Pikmin.
Mario 151
Luigi 142
Peach 134
Bowser 162
Yoshi 147
Rosalina 128
Bowser Jr 155
...
So the conclusion may be (@

the first one could possibly be confirmed by you in order for updating your awesome guide)
1) Uthrow does 12.5 instead of 12. I did at least 20 tests about it and I get the same.
2) Uthrow isn't affected by move stale (always does 12.5 even when you spam it without another movement)
So ... the only thing that is left to do, is to test this results in another stage.
I could do it but first I need to confirm these 2 things so I'm counting on you guys.
