I like to punch down every couple of hours during the day. Since I'm now retired, I'm home during the day and have time to do this. I think it helps to keep the grapes hydrated and contributes to body and color which in my case is not a problem because I like big reds. On YouTube there's a video showing a winery (I think it's CrushPad) that uses a plate the size of the fermentation tank to keep their grapes submerged throughout the entire fermentation.
