Sleepyhead not Averaging Nightly Sleeps
#1
These are my results from last night according to Sleepyhead.

Whole night AHI 8.83

First 6 hours AHI 4.81

Last 75 minutes AHI 4.03

Now it looks to me as if SH has added the two AHI's together to get a final result. But if I have two consecutive AHI readings between 4-5 surely the average is between 4-5, or is it?

I remember a recent thread that questioned how SH calculated it's figures but I couldn't find it. It might have been on a different forum.

Any insights or have I just experienced my first <AHI 5 night?

Hi Holden4th do you know FJ or EH Holden
Anyway enough smart-arse

If yo check out my Thread re Session Information AHI I also raised note "Palerider" has posted that is a bug been fixed but I still have not been able get my Sleepy head to show AHI for just the individual session hrs times.

My SH also calculates individual session Events over / the Total session hrs. So if you then them to get will the whole nights (combined sessions) average AHI.

Example: AHI being Events "CA + OA + H"
Have calculated that SH has calculated figures as:

SH Session 1 = 37 events / session 1 & 2hrs(7hrs 42min) or 7.7 and equates to 37/7.7 = AHI 4.81 Rounded

SH Session 2 = 31 events / session 1 & 2hrs(7hrs 42min) or 7.7 and equates to 31/7.7 = AHI 4.03 Rounded

SH Combined session 1 & 2 = 68 events / session 1 & 2hrs(7hrs 42min) or 7.7 and equates to 68/7.7 = AHI 8.84 Rounded this the correct AHI for the combined session Total Session Events / Total hrs

Actual individual evens to calculate should be :

Session 1 = 37 events / session 1hrs (6hrs 24min) or 6.4 calculates to 37/6.4 = AHI 4.81 rounded

Session 2 = 31 events / session 2hrs (1hrs 18min) or 1.3 calculates to 31/1.3 = AHI 23.85 rounded

SH Combined session 1 & 2 = 68 events / session 1 & 2hrs(7hrs 42min) or 7.7 and equates to 68/7.7 = AHI 8.84 Rounded this the correct AHI for the combined session Total Session Events / Total hrs

that's because you haven't downloaded the V1.0.0beta1 version.

you're still using an *OLD* version (0.9.8-1)

Yes Palerider hadn't downloaded it properly and gave up but have had another go Little Ripper the New Beta Sleepyhead version is now up and running, and Yes has fixed the AHI session information problem as you said ? Thank you keep up the good work Smile

So Holden4 use links from Palerider's post and will fix your problem Mate.
