Have no idea what you're asking.
Assume you've read the rules, but it sounds like maybe you haven't.
Your score is the efficiency you get.
Efficiency is the weight of the load carried divided by the weight of the boom.
So, a 15gr boom, carrying 15kg (15,000gr) has an efficiency of 1,000; scores 1,000. An 8gr boom carrying 8kg (8,000gr) also scores 1,000. A 12gr boom carrying 14.5kg (14,500gr) scores 1,208.33, and so on. So, going really light and carrying partial load, or going heavier and carrying heavier load can get you the same place- up to you how you want to approach it
Does that answer your question??
