Help me understand RNP SAAAR sir. What is the difference between RNP
0.10 and RNP 0.30 in the minimums boxes of the IAP?

Sir, the minimums to be used are those corresponding to the RNP for which the
crew, operator, and aircraft are authorized. Thus, if the crew, operator, and
aircraft are authorized for a RNP of 0.10, they will use the minimums
associated with that RNP on the plate; if they are qualified only for a RNP of
0.30, they will use those minimums instead. Notice that the minimums are
lower for more stringent RNPs.

If you have a SAAAR RNP authorization, you already know this. If you don't
already know this, you don't have the authorization, and so it doesn't matter,
since you cannot use this SAAAR approach.

Reference the AIM and AC 90-101 (from which the AIM text is largely lifted)
for further information, or just google for it.
