I rerun some of tests. There are index build times in seconds for old way
of parent refind and new way of it.

old new
usnoa2 2385 2452
usnoa2_shuffled 8131 8055
uniform 8327 8359

I thinks difference can be described by round error.
Indexes seem to be exactly same. It's predictable because changing
algorithm of parent refind shouldn't change the result.
