RE: (12C Platinum) Internal Precision Test
It might be interesting to refer to some calculations in Mathematics Written in Sand, by William Kahan. See especially from Page 15, "A Penny for your Thoughts" which is a FVM problem with very large n.

Notably, the HP12C, although returning the same value in the forward direction, comes up with a slightly less accurate answer than 4 other HP models when recalculating i.

Edit: see also this post for the example.
