    if you see a overflows in you table snapshot ...

    That is only one of the reasons you may want to do a reorg. otherthan that, cannot think of anything else ..

    But, why don't you want to do runstats ?

    I read my post now and see I have not been clear ..

    Overflows in table snapshot may point to the requirement of reorg.

    As far as I can think of , this is the only metric that you can use to identify reorg requirement without doing runstats
