Changing the model treats all N openings at the selected rate. It does not identify past Treasure Hours openings or change your saved counts.
How to read this estimate
The cumulative estimate is 1 − (1 − p)N. Expected awards are N × p, not the number of rewards you have won. N × p is also a small-count approximation to the cumulative probability, not an exact equality. Your log may span different weeks, chest types and boosted sessions. Epic has not published the full random process or separate odds for each chest type. More openings do not improve the next chest's base rate. The 7.5× gold multiplier is a reference scenario; a specific Treasure Hours session can differ.
