Hi HappyHiHy:

___I know EricBecky posts both his actual and dash results in the notes section of each tank for his Insight as do many others. It might be worth a look at a few members DB tanks among the many in the GH RHMDB to see where the Display vs. Calculated actually lye.

___Another item is this discussion has been batted around more then once here at GH. I bet you find what you are looking for with a few hits of the search function?

___Good Luck
