Why did my BTC short stop loss get absolutely nuked

I opened a BTC/USD short:

Entry: 93,167.44
Size: 0.0400 BTC
Stop Loss: 93,726.44
Take Profit: 92,049.43

Based on math, if my SL was hit I should’ve seen:

SL SHORT @ 93,726.44 PnL = -22.36

But instead, the actual execution was:

SL SHORT @ 94,109.69 PnL = -37.33

That’s **\~380 points of extra pain past my stop**.

Is this just normal BTC slippage during volatility, market-order stop behavior, bid/ask nonsense, or broker execution delay?

Trying to understand *why my “defined risk” wasn’t actually defined*.
