@khohanguc By tradition of sorts, the milestone weights with kettlebells are the 32 and the 48. Mainly, I think, because the 32 is the heaviest of the "normals" and then the 48 is the heaviest of the heavy (even though you can buy even heavier bells, up to 92 kg).
It's not a fair standard, nor is it an actual standard. The names are because somebody said "it's simple and sinister" and Pavel liked it and used it. Things need names and sometimes the names make us think there's something more there. If the 32 was called "Red" and the 48 "Blue", you'd feel differently about them.
Nobody here should be judging anybody based on whether they've reached Simple or Sinister. But if you get Simple done at 63 kg BW, good job! Bodyweight definitely matters. One sort of a standard is pressing half your bodyweight, so BW is definitely not ignored in everywhere.
