What it computes and assumes

Each synthetic day has your trades per day; across them, the share that wins your average win is your win rate and the rest lose your average loss. With decimals, some days have one more trade than others so the average is yours.
The report's simulator resamples those days and checks every daily close: first the daily limit, then the total one and last the target with the minimum days. Every day with trades counts as a trading day, even when it nets zero.
Every win and loss has the average size: no tails, slippage, costs or intraday floating loss. Real losses vary, so with a real history the limits are usually hit more often.
Trades are independent: no streaks longer than chance.
The rules are those each firm posted on the date shown; they may have changed.
