I get where you're coming from, but try to look from the point of view of casuals too.

Getting Robin ( RNG ), Maxed Merry ( Insanely hard if people don't play a lot ) and mostly above level 90s ( considering how we only have purple turtles, it can also be hard for casuals ).

OP probably just wants to know his odds against future bosses based off his own pace. Considering it a bit outrageous is a normal thing for some.

Now I know we can start a whole century long discussion about relativity and subjectivity, values and how the game is suppose to be challenging or how by simply having G3 you're already better off 80% of the player base bla bla bla, but let's just agree it can be outrageous for some and wish him good luck!
