Calculate success rates for gear upgrades with seeded rates
IMPORTANT!
Success rates show PROBABILITY, not GUARANTEES:
40% success rate means:
• Each attempt has a 40% chance
• Over many attempts, ~40% will succeed on average
• You could succeed 10 times in a row
• You could fail 10 times in a row
It does NOT mean:
• "4 out of 10 will always work"
• "If I failed 6 times, the next 4 must succeed"
Think of it like rolling dice:
• Each roll is independent
• Past results don't affect future attempts
• Bad luck streaks happen (and so do lucky ones!)
