If I may be so bold Mike...

I presume that you mean to "use it during development" **primarily** to confirm that the Select(s) in question are OTHERWISE fully optimized. In other words, it may not be safe to ASSUME that a report of partially optimized is caused solely by the absence of a TAG on DELETED().

Cheers,

>However, without a deleted tag, sys(3054) will never report full optimization. So, use it during development and stop during production.
