# Methodology

## Population

JK7 tenant2376 users with a validated first successful recharge, at least one settled game in the first recharge cycle, a complete D1-D7 observation window, and a final first-cycle balance strictly below the balance before the first game.

## First recharge cycle

From the first successful recharge through games strictly before the second successful recharge. Later cycles are excluded.

## Peak profit percentage

`(maximum balance during the first cycle / balance before the first game - 1) * 100`.
The peak is an interim process state. Every included user still finishes the cycle below the starting balance.

## D1 recharge retention

At least one successful recharge on the exact next calendar day in `America/Sao_Paulo`. Login, game activity, and same-day repeat recharge do not count.

## Interpretation

All results are descriptive associations. Peak experience, rounds, turnover, deposit size, game mix, and user/channel differences may be correlated.
