yes a actual sheer strength is between the 2 adhesives is aprox 25%-30% but in real life situations 1900psi http://www.devcon.com/prodfiles/pdfs/fam_tds_175.pdf Vs. 2500psi makes no difference since the load it would take to get to those pressures would destroy a model before the adhesive would fail, which was really my point.

having used both speeds to work with gluing tail feathers, critical surfaces in modeling and in const. you better be a assembly ninja to pull wing joining off with it,
but some of these areas where I have used it have yet to fail under high loads, and the quicker glue can actually be a advantage when gluing a properly fitted part over needing to hold a part in the proper position untill its tacked up, there are alot of postings that seem to imply that there is a significant apparent strength difference which there isn't.
