[Max/Painter] What affect does extra hi-poly geo have on normal bakes?

Dubious_Fellow

Hi, I have a low poly strap which fits around a pole. The inner-facing (unseen) polys have been removed like so:

The high poly still has its inner-facing geo:

If I were to try baking the normal map now (without removing the hidden polys on the high-poly model) would it produce baking errors?

**I would do a quick test but I'm putting off downloading Painter for as long as possible due to budgetary constraints**

Thanks in advance...
