I agree with Roy; it is my sense also that 216 prescriptions would cover 90% of my prescriptions written. (Then again, why not 270? 324?)
However, when using the registry, doesn't it just populate with the most recent Rx's you have written?
If so, then all your good old reliable customized Rx's can be pushed off the top 10 list by a misspelled version that your nurse entered. You would have to be vigilant to make sure your entries didn't get corrupted.
I would prefer to have a customizable database
a la the original thread "Improving AmazingMeds":

Still, an expanded registry would be
something at least. It would work when it worked. I would be willing to give it a try. It doesn't seem like something very difficult, does it?
