The estimate statistics will overwrite the stats generated by the earlier compute.

We have a database set to CHOOSE. Although we would like to run compute statistics weekly on a particular schema's tables, it takes too long. If we were to do compute statistics once per month and estimate statistics weekly, would that be efficient?  When estimate statistics is done is it overriding all of the statistics from compute statistics?
