How Does the Concept of “Slippage” in Options Trading Relate to the Loss of Potential Earnings from Rejected Shares?

Slippage in options trading is the difference between the expected price of a trade and the actual executed price. The loss of potential earnings from rejected shares (stale or invalid) is analogous to slippage because it represents the difference between the miner's expected earnings (based on their raw hash rate) and their actual earnings (after rejections).

The rejected shares represent "lost" execution of work.
