Deflected…
You might be confusing the functions and responsibilities of the PE and a separate QC reviewer. As the PE, you are responsible to check any and all work that will receive your stamp, whether done by an EIT, a subordinate PE, or by yourself. So, if an EIT is doing a calc for you, you should have an appropriate level of input from beginning to end of the calc process. For example, you should establish the criteria and objectives for the calc, provide relevant information, answer questions, and, yes, check the final product.
If your company has a formal (or even informal) QA/QC process, then another PE, with at least your level of experience, will be called upon to review the project at some level of detail. In my experience, minor calcs don't usually get reviewed, but critical calcs should be separately reviewed along with the plans and specs.
I hope this helps.
