Teradata 13.10 Statistics Collection Recommendations - comment by padhia

Hello Carrie,
 
Is collecting stats on (PARTITION, PI) or (PARTITION, PI, partitioning column), subject to the 16 byte limit of multi-column stats? That is, if a table has a PI that is on a really long set of column(s), will the stats on PARTITION+PI be misleading to the optimizer if the first 16 bytes aren't distinct enough?
 
Thanks!
