And a further follow-up. IMO go with the caulked-on glue.
After we finished the 4-gallon bucket, we had a medium closet area of flooring still to install. We switched to a caulk gun to compare instead of opening another large bucket. The difference in ease and speed of installation was orders of magnitude better in those last rows. And it turned the job into a one person instead of two person job. We still were able to get great coverage.
This troweled-on glue may have advantages if you're going to glue flooring to concrete or have some challenge that needs the VOC's or for some other application.
But for our installation, wide-plank oak on plywood subfloor, it just wasn't worth it. Not only was it terribly expensive, It cost us many, many hours in extra time, even though we worked out a good method and enjoyed the glue operation. The time hit is just not worth it with troweling.
