Is gradient lag fixed in 540/840?

Waiting to hear about user experiences with gradient lag.

    Looking in the videos from GPLAMA - it seems not...! 

    But this may be related to early firmwares?

    I feel like I'm missing something as I've seen this a few times in different places.  Is gradient lag an issue?  I use climbpro on known routes and can eyeball the gradient changes, but I feel like I may be missing a use case where it being quickly accurate being important?

    In direct comparison on my last rides, it is MUCH faster to change to a more seemingly accurate value than my 830.  The extremes are also less (eg. 830 will register +/- 11% whereas the 840 shows +/- 10%)

    It's way slow on mine.  I was using the Sensible Grade IQ app previously which was way better, but not yet compatible with the 840.

    . To be clear, I am comparing stock Garmin grade field on 830 (v9.75) to 840 (9.09). I’m assuming you are comparing Sensible Grade IQ on the 830 to stock 840?  I look forward to trying Sensible Grade when it works on the 840.

    We should soon have something better that anecdotal that looks at grade behavior.  DC Rainmaker is going to post a review of 540/840 grade behavior in the next few days. "So I’ll be putting this to the test over the coming days, alongside gradient reaction time as I’ve been doing recently for the Edge 540/840 units in those reviews. All of which should result in a nicely refreshed ‘Best Climbing GPS’ post/video shortly." This is from a comment at the end of a just posted quick review of Wahoo's new Summit Freeride feature.
