For Roblox Jailbreak, 30 robberies is about 4.0% of the way from level 4 to level 5 if you use the commonly cited “big server” pity value of about 750 robberies for that level-up range. That comes from 30÷750×100=4%30\div 750\times 100=4%30÷750×100=4%.

What that means

  • 30 robberies = 4% progress toward level 5 in that estimate.
  • If you’re playing in a small server with a lower pity target, the percentage would be different because the required robbery count changes.

Quick note

The Jailbreak community discussions show that the level 4 pity/progress numbers can vary by server size and tracking method, so this is an estimate rather than a guaranteed exact value.

TL;DR: 30 robberies is roughly 4% from level 4 to 5 in the usual big- server estimate.
