We noticed a big difference in # of control reads between regions so we had our Roche tech out who said it was the PTP cartridge that was bad (installed for the Ti "update" in Dec 08). Since then, we see the same problem (i.e., large differences in controls reads between regions). Any ideas? We didn't have this problem until the release of Ti (Nov/Dec 08) and we see it on both FLX and TI.
Thanks for your input.
