I make my benchmarking code available. What if d is a constant, but not known to the compiler? Can we do better?

Waits and Queues has been used as a SQL Server performance tuning methodology since Tom Davidson published the above article as well as the well-known SQL Server 2005 Waits and Queues whitepaper in 2006. Detailed query-level waits are available on demand via integrated Plan Explorer. Most Queries Don't Wait.
