waterfall rate slower now

It seems to me the waterfall rate when the Slider is at 100 and you zoom in is slower than it is displaying. The scale has a marker every 2 seconds and I am timing the waterfall at over 3 seconds in that span.

Measuring method
I take a horizontal line in the waterfall produced by noise and I start the stopwatch when it reaches 2 seconds and stop it at 4 seconds. I know I will not be exact, but it is consistently in the 3 seconds range

The Scale changes depending on the rate but anything between 86 and 100 rate will still keep the scale at -2, -4, -6, etc... which is odd. There isn't a clear direct relation between the rate number and the actual speed.

The slower pace of the waterfall was noticeable to my **** eye because before I could easily see the dots and dashes on CW and now they get "mashed" together.

When I zoom out the speed goes back to the correct speed. I can time it with a speed watch and it is consistently 2s vs the 3s when I am zoomed in.

    We timestamp the spectrum data as it is received from the radio.  I'd like to hear if others observe this same behavior before entering it as a defect.

    Thanks Nordic! Good to know I am not going completely crazy already.

    Thanks Tim. I feel the same way... I am also very hesitant to call something a defect unless it is seen by others... therefore the sharing with the community.

    I'll be out of town starting this afternoon so I won't be able to verify until Sunday. I'm sure it will be verified either way by others before then.

    Hi all,

    Salvador, following your stopwatch procedure, timestamp is correct in my 6300. Tested for a 10 seconds period.

    My system: Core i5, Windows 10 pro anniversary update, 24GB Ram, 456GB SSD, Video card Gigabyte GT730 2GB DDR5.
    All drivers provided by the operating system (installed from Zero).



    Hope usefull ;-)

    Full zoom in, no difference. tested now 20 seconds, Android chronometer showed 20.4 sec (possibly not accurate because of the tactil interface. If necessary I can borrow a sports stopwatch from my wife). 

    By the way, SSDR full zoom and full screen on 29" LCD.

    Best Ni
