I should have been more clear. Too much catalyst dissipates with an acrid, almost vomit type odor, often accompanied by a pinkish color shift and/or haze. This is a different smell than the normal outgassing of formaldehyde. In my opinion, companies that use a diluted catalyst are just trying to sell more product. A gallon of catalyst at 3% lasts a lot longer than a gallon at 10%. 3% ratios are not difficult to measure with reasonable accuracy.
Crew weight. There is a wide range of crew weights that is competitive in the Viper 640. The average of all crew weights at the 2015 North Americans: 550 lbs. Crew weights ranged from a low of 490 (#10) to a high of 650 lbs.
Total work load: 2,375 pounds (95 pounds x 5 reps = 475 pounds. 475 pounds x 5 sets = 2,375) Here is the work load if a beginner performed higher rep sets, assuming a work weight of approximately 60 pounds for 12 reps. 60 x 3 x 12 (60 pounds, 3 sets, 12 reps each set)
