+/// @brief Return the estimated time an MCBIST subtest will take to complete
+/// Useful for initial polling delays, probably isn't accurate for much else
+/// as it doesn't take refresh in to account (which will necessarily slow down
+/// the program.)
+/// @param[in] i_target the target from which to gather memory frequency
+/// @param[in] i_bytes number of *bytes* in the address range
+/// @param[in] i_64B_per mss::YES if the command is 64B, mss::NO if it's 128B. Defaults to mss::YES
+/// @return the initial polling delay for this program in ns
+///
