It covers five system spread types, represented by 20 numbers totaling 100 percent, and shows how custom spread profiles can be created using evenly distributed or manually weighted slices with optional normalization. It then details the calendar tab, including working days Monday to Friday, daily hours, and a holiday list of 21 dates, to ensure durations count working days rather than calendar days. If the calendar tab is skipped, simulations fall back to a plain Monday to Friday schedule with no holidays, causing finish dates to drift optimistically.
