I have not, but most of the waterborne finishes can be sprayed with the proper thinning. I wouldn't thin it more than the manufacturer allows, you might screw up their chemistry.
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.

The quick and dirty answer is: sure it can be sprayed and most often is. In many cases it does not need to be thinned. As Fred says, most manufacturers have limits as to how much water can be added. Add too much and you will mess up the chemistry and you won't end up with a proper film.
Bottom line is that spraying is the best way to apply a waterborne acrylic finish. Brushing and wiping can be problematic as the finish dries too fast to flow out and brush marks will result.
As always, test it on some scrap before committing to your actual item.

The upper limit is generally 5-10%. Add too much and you will mess up the chemistry and you won't end up with a proper film. Water is not truly a "thinner" for waterborne finishes. It's a carrier of the other chemicals and is intended to keep those chemicals apart until the water evaporates allowing the finish to coalesce into a dried film.

Yes, it sprays fine. I've sprayed it with a 1.4 mm tip HVLP gun. Sorry, I can't remember if I had to thin it or not, but I don't think so. Polycrylic would not be my first, second, or even third choice for a dining room table, but it sprays fine. GF EnduroVar or Enduro Clear Poly would be a much better choice, IMHO.

You are over thinking things! I have a HVLP turbine rig and 95% of the time need not thin. I use distilled water a mine .has very heavy mineral content. I just use the default tip.
Check viscoscosity to/ see if you have the right tip or need to thin.
