I think it is more important to know the working load and breaking strength of the tie-down.
My D-rings mounted in the trailer floor, backed by a steel plate welded to the frame are rated at 5,000 lbs each. My rule of thumb is that each strap working load is equal to or greater than the bike weight. I use 4 straps going forward, 2 from the lower tripple tree and two from the passenger pegs. I use two staps going to the rear, one from each passenger peg. I replace them every 3-4 years. I have one zippered bag where I store the soft ties and straps. I also carry a couple of spares.
In a panic stop you'll probably pull between 1.2 and 2 g's, so that 850 lb bike is trying exert 1700 lbs of force (at 2 g's) that the wheel chock and rear tie downs have to hold. If the breaking strength is 3 times working load then a 900 lb working load strap will have a BS of 2,700 lbs. In the example the two rear straps will be within their combined working load to keep the bike from moving forward. That gives you 3,600 lbs of reserve strength.
I do conpress the front springs, just not completely. The rear tie downs go out at a 45 degree angle front the peg, one set of the front ties do the same.
