Think of it this way. Whenever you delay your order, you have either a loss or a gain.

There are two components to this delay in the CFAI curriculum: Delay Costs and Realized GnL.

The delay costs refer to the difference in the prices when you decided to place the order (revised benchmark price or decision price, same thing) and the original benchmark price. The Realized GnL cost refers to the execution price and the revised benchmark price or decision price.

Delay costs always refers to the original benchmark price and the realized GnL refers to the revised price.

Since in this 11b example there were some shares purchased on Monday, no delay costs for Monday, notice its 0%.

Delay costs exists for tuesday because there were trades executed on Tuesday that were intended to be executed on Monday. That's the delay.

Let me see if I can summarize what I just said.

Delay Costs (difference from original price to next day open)
Realized GnL Costs (difference from the current day's open and the current day's execution)

Hope that helps.
