Game Mechanics: Research success rate

[Obrae]

Sad tale of a magician (not me)

So i trivialize 29 pet combine
Magician hand me his combine mats, i fail
I feel bad
I raise a pet to 29, i fail again with my mats
I raise a pet again to 29, i fail again with my mats.

back to back to back 5% fail chance ? that is BS, possible but BS.

I speak to mage community i get report of fail trivial combine by the dozens with very little combine attemps.

Defenitly fail rate is way too high. Just another BS abiout actual Magician position.
I guess its testable by the staff, i have no hope they do, posting by principle.
