#39 No Data on Leak Graph

[Sleepster]

No leak rate data showing for my PRS1 Model 650P BiPAP. I'm running v0.9.1 on a WinXP machine. The leak rate data is there for my Model 450P CPAP, though. (I switched machines awhile back.)

ah ok.. I know what's causing this now...

It's trying to show the dodgy unintentional leaks calcs and they aren't there for bipap, only total leaks..

(I can't calculate unintentional leaks for anything other than CPAP yet without having formulae for specific mask types. )

I'll test the auto-updater in the next day or so and hopefully bring you a fix..

Still no data on the Leaks graph on the Overview tab, v0.9.2-1 for the bipap. Data is there on the Total Leaks graph, though.

There is not supposed to be.. (yet) Your machine simply does not record unintentional leaks, so I have to try and calculate them from Total Leaks.

Encore calculates them off Mask Profile formula I don't have access to.

That graph should not be showing at all, unless you run occasionally in plain CPAP mode. Currently, SleepyHead can only calculate unintentional leaks from Total Leak data for CPAP mode.

I'm working on an algorithm that can detect unintentional leaks without requiring knowledge of Mask Profile. (It basically creates the mask profile from studying the leak data) I'm not sure how well it's going to work..

I found this in the commit log...

8863523 Sun Jan 15 16:20:10 2012 +1000 Initial PRS1 Unintentional Leaks hack for all CPAP modes. Minor crash fix to UserFlags calculations

Is this really a bug or is it a feature request for something the PRS1 doesn't record?
