Formula to Account for Weekend Days for an SLA

Have a look at the V2 file I uploaded. It's got all the deidentified data. It's filtered to show upload days = Friday and Interp days = Monday, Tuesday or Wednesday.

What's the difference between ID 632 and 633? Both were uploaded on a Friday and interpreted on the Monday. Yet 632 says it's 1 workday and 633 says it's 2.

Images that get uploaded on a Friday and interpreted on Saturday or Sunday should be considered "same day" or 1 workday. Images uploaded on a weekend and interpreted on Monday should be considered same day or 1 workday, Tuesday would be 2 workday and Wednesday would be 3 workdays.

Does my logic make sense?
