Gunite pool renovation did a core test, any thoughts. Pools 5 years old and no creaks. Just new marble dust, don’t think I can?

Welcome to TFP.
Interesting report.
Why did you do the tests?
What are you looking to determine?
Minimum gunite PSI strength desired is 2500 although shotcrete at 4000-5000 is preferred.

Some of the strength looks low.
The strength numbers should be the same +/- about 10%.
Why the difference?
The variation is concerning.
What were the original specifications for the gunite?
There's not much you can do about the strength at this point other than remove and replace.
Why a replaster at 5 years?
It is odd to do these tests at 5 years without a reason.
What prompted the tests?
What does the original builder say?
What warranty is on the pool?
What does the current builder recommend?

5.5" thickness seems a little bit low.
