I work full time, plus double downing on your product.   That's my level of commitment!   :-DD  Sleep, what's that!  :-DD

Using the demo mode and comparing the previous version,  there is a slight improvement in the contrast.  It seems you feel this is one of the main selling points.  Before I spend time changing my review,  I want to make sure that you are satisfied with your software.  I can certainly postpone the review if you feel you can improve it.   

A bit of advice, because I assume you actually want to leverage these reviews for sales, in my experience, if I make a multi-part series,  the first and last videos will see the highest view counts.  If we make a follow up video showing software improvements, I doubt it will have half the views.  IMO, you really only get one chance at it.   For me, this isn't really a problem.  It's a small channel and isn't there to make money.  IMO, it is something you should consider.   Give it some thought and let me know.

Enable color grading, then disable the channel, waveform is still displayed.   Disable still works when color grading is turned off.   

Saving the defaults does not store the state of the color grading when it is selected.

Currently this is due to the way some algorithms (e.g. histograms) and display (e.g. OpenGL buffer size) are implemented. This limit can be drastically improved (to the ~million scale); it's just a matter of priority, and putting the work in. We can have it in by next update if you find it important.

My only goal was to improve the contrast of the eye by adding more data (further slowing down the collection).  It is more if you find it important.  It may not help.

The demo mode uses a simulated (idealized) eye diagram, and the contrast is already good with default settings. You will likely see a larger contrast improvement when using the actual hardware.

Fair points. Perhaps the single largest area of improvement is the sweep speed (as you mentioned in the review). As we estimated in our reply #282, it is theoretically possible to make the sweep 10-100x faster with careful firmware optimization.

We suspect this will take 2-4 weeks to get right and thoroughly test, but it will make a qualitative change in the viewer's first impression. It may be worth waiting until this improvement to post the review.

As a middle ground, perhaps you could link the (unlisted) current version of the review here. This will let the community members here voice their thoughts, and suggest anything they'd like to add. We also suspect that those who are following the thread closely enough to see the link will also watch an updated version when it becomes public.

Both fixed in below prerelease:
https://gigawave-releases.s3.us-east-2.amazonaws.com/GigaWave_v2.5.10_PREVIEW_2022-02-18_Windows.zip
Note that this feature will go through our normal QA process later this week, before the public v2.5.10 release.

For this purpose, increasing this limit will likely not help. 3072 points is already finer than the pixel resolution of the display.

I have updated the review to include the new software with the color grading feature.
