So Wolfgang,

in that case, should _wait_ till table stats (which are probably estimate) are complete to perform index stats (which you recommend compute) or can that happen in parallel.

One reason to collect index stats separately would be if you use estimate for the collection of the table statistics. In that case I collect the index stats separately with a compute. Index statistics collection is fast enough to always go for exact statistics rather than sampling.
