I've seen a lot of people recently guide at 0.5s or 1s or some short duration in an area with bad seeing. The guide scope then chases the seeing

You will note i mentioned earlier thet Metaguide has a quasi stacking function to get around this, but i am still playing with it.
Basically, Metaguide uses frames at 0.5second intervals when not guiding, but when you guide, you can select the actual guide freq and averaging you want to use. ( ref the integration mode in the help )
In this mode, lets say your camera grabs data at 15fps
You may tell it to average 10 frames and then guide at 1second.
The guiding uses the centroid of the integrated image
thus ( hopefully ) averaging out the seeing.
