The top clear cover governs the design so spacing and side cover are not a factor. Any other case would make (cb+ktr)/db = 2.5. We don't really have the beam to column case on our project so no 7' columns. I added that example because any example problem or document I found while researching...
Thanks for the response steveh49! In this case I am the client and I am reviewing the design drawings and rebar fabrication drawings before they are IFC. You're right that the percentage is based on the total bar length so the total decrease in material will not be 37%. Although, in some cases...

In my mind the development location is "inside" the...
