Mike, I noticed something that I think is related to the null values being reported in the database. Every now and then when I hand off to the next site, I will get this:
The GCI and TAC data are missing. It will stay like this for 2-5 seconds before the rest of the data populates. I noticed that when I have null values in the DB the PCI is the only value reported.
Not sure what would be causing the delay but I thought I'd share my observation. Has anybody else with the null values problem noticed this as well?
