You can decide the stat collection frequency based on the following criteria
1. The row count change (# of rows)
2. Number of unique values changing
If it's a static table then you don't need to collect frequently. Also other than primary and secondary indexes, you should collect stat on columns used in the join conditions.
Hope this helps.
