Strange Sleepyhead results

I'm getting some results that seem odd to me re: the pressure statistics vs. the graph. For example, one night, the pressure statistics are Min:9.10, Med: 8, 95%: 11 and Max: 11.5. These seem strange to me even on their own - how can the min be lower than the median? And why would the min be 9.10 if the machine is set to a min of 6?

And then, there's the accompanying graph:

(Hopefully this works...)

This is from the same night. It never shows the pressure going as low as the stated min, or the stated median (let alone the actual machine min). Also, clearly the majority of the graph is showing a pressure above 11, despite the 95% number, and a max well over 11.5. Am I reading this incorrectly, or is there something strange going on?

While I've got some nights with strange data in that vein, I've got a couple of others like this - Min: 10.20, Med: 7.90, 95%: 12.00, Max: 12.60. Again, the min and median numbers seem bizarre on their own. And then the graph:



Here the max and 95% numbers seem to be represented properly, but I can't see most of the graph as it falls below the bottom line...

Machine is a PR System One 561CA, computer is Windows 7, and SH version is 0.9.3. Any help would be appreciated, as I find this very confusing! Thank you!

not relevant

There are some known bugs in how SleepyHead works with the Series 69 System One machines like your 561 model. The statistical numbers are likely being incorrectly calculated due to a bug. You might want to file a bug report at sourceforge.com and see if you can provide the same information over there. JediMark does read this forum, but not every day. The bug reports filed through sourceforge get to him in a timely fashion.

Ah - I thought they'd been resolved in the 0.9.3 release, but maybe not all of them. Just wanted to make sure I wasn't missing a setting or just reading totally incorrectly. I'll file a report, then. Thanks!
