i guess this wikia page is not a hacker resource. we don't need investigations on server side percent values. they are low for sure.

Kabam gave us that upgrade chance bar with 4 colors

say green - very good chance, yellow - several breaks possible, orange - many breaks possible, red - nearly impossible to upgrade.

Kabam made this for more money, and that's how they probably think - level 1 - green without platinum, level 2 - more breaks, level 3 will take your time, level 4 is for really patient players. and 5 is where you start using x60 boost. even with x60 part still not gaining 100% chance. if tooltip of the boost not lies, and it actually multiplies your upgrade chance by 60, original upgrade chance must be around 1% for level 5 and above.
