So the slight angles from us straight strappers also help mitigate some side to side action based on what you just said. Why would I still cross them then if my slight angle works to help reduce side movement if that would further compromise my fore and aft protection?
You keep mentioning how much load capacity being lost due to angles is minimal but you won't provide the math you use to come to this conclusion. The greater the angle of the strap the quicker that strap can reach its WLL. So why risk that if as you say the goal being to reduce your handicap as much as possible for all possible scenarios?
Since you have not read the entire thread I will offer it one more time. 45 degree angles net a 30% reduction. Lesser angles, lesser reduction. Most are likely losing somewhat because you rarely see true 90 degree inline strapping employed on a car trailer. Most quality straps will be well within the safety limits no matter the angle in our usage. If your goal is zero loss then your only recourse is to employ more anchor points...your call.
Life is full of compromises. Angles overlap one another...inline do not.
