Inaccuracies in Encore Pro software

After reading Derek's review of Encore Pro software, I thought it important to call to everyone's attention who uses it the following information in his review. I find the second point really important as it relates to overall indexes and rounding up that the software does. Hope this helps you understand what the software is doing and how it is inaccurate.

Note on the Accuracy of Data Presented in Page Three of the Report
I have found two "bugs" in the data presentation on Page 3 of the report (Summary of Long Term Trends):

The Flow Limitation Index (FLI) graph is "flat-lined" at zero, that is it shows zero flow limitations, regardless of the information contained in the daily reports. This can be seen in the sample sheets given above, where the average FLI is given as 1.2, but the graph shows no flow limitations on any of the six days in the report.

The data plotted is inaccurate on all plots. The problem appears to be that the data representing all of the indices is "rounded-up" to the next integer value before being plotted and reported on Page 3. For example, on the final night of this study a single apnea was detected in a session of 8 hours 33 minutes. The Apnea Index (AI) should have been reported as 1/8.5 (or 0.1), but it has been rounded-up by Encore Pro and is shown as 1.0. Similarly, the average AHI for the six nights of this download is actually 0.94, but because each night was rounded up before averaging, the value shown on Page 3 is 1.4 - a 50% error (This error will be less significant for higher values of the indices.)
