I was really delighted by the detailed information about drop chance calculation. I've been meaning to throw out some tables as thanks, and I've now got them together. I've assumed based on the description that each armor piece has all multipliers applied to the base rate, then all armor piece rates are summed, and then the check is made against the totaled penalty. I've generalized as "ticks", but I assume that the drop chance is each second. My results probabilities are very rounded. Here is how the probabilities line up:
Base drop chance = 1%
Light chest armor only (4% drop chance per tick): 1 tick with no drops 96%, 10 ticks with no drops 66%, 30 ticks with no drops 29%, 60 ticks with no drops 9%, 120 ticks with no drops 1%
Medium chest armor only (6% drop chance per tick): 1 tick with no drops 94%, 10 ticks 54%, 30 ticks 16%, 60 ticks 2%, 120 ticks 0%
Heavy chest armor only OR light vitals only (8% drop chance per tick): 1 tick with no drops 92%, 10 ticks 43%, 30 ticks 8%, 60 ticks 1%, 120 ticks 0%
Medium vitals only (12% drop chance per tick): 1 tick with no drops 88%, 10 ticks 28%, 30 ticks 2%, 60 ticks 0%, 120 ticks 0%
Full light armor (14% drop chance per tick): 1 tick with no drops 86%, 10 ticks 22%, 30 ticks 1%, 60 ticks 0%, 120 ticks 0%
Heavy vitals only (16% drop chance per tick): 1 tick with no drops 84%, 10 ticks 17%, 30 ticks 1%, 60 ticks 0%, 120 ticks 0%
Full medium armor (21% drop chance per tick): 1 tick with no drops 79%, 10 ticks 9%, 30 ticks 0%, 60 ticks 0%, 120 ticks 0%
Full heavy armor (28% drop chance per tick): 1 tick with no drops 72%, 10 ticks 4%, 30 ticks 0%, 60 ticks 0%, 120 ticks 0%
Base drop chance = 2%
Light chest armor only (8% drop chance per tick): 1 tick with no drops 92%, 10 ticks 43%, 30 ticks 8%, 60 ticks 1%, 120 ticks 0%
Medium chest armor only (12% drop chance per tick): 1 tick with no drops 88%, 10 ticks 28%, 30 ticks 2%, 60 ticks+ 0%
Heavy chest armor OR light vitals only (16% drop chance per tick): 1 tick with no drops 84%, 10 ticks 17%, 30 ticks 1%, 60 ticks+ 0%
Medium vitals only (24% drop chance per tick): 1 tick with no drops 76%, 10 ticks 6%, 30 ticks+ 0%
Full light armor (28% drop chance per tick): 1 tick with no drops 72%, 10 ticks 4%, 30 ticks+ 0%
Heavy vitals only (32% drop chance per tick): 1 tick with no drops 68%, 10 ticks 2%, 30 ticks+ 0%
Full medium armor (42% drop chance per tick): 1 tick with no drops 58%, 10 ticks 0%, 30 ticks+ 0%
Full heavy armor (56% drop chance per tick): 1 tick with no drops 44%, 10 ticks 0%, 30 ticks+ 0%
Base drop chance = 5%
Light chest armor only (20% drop chance per tick): 1 tick with no drops 80%, 10 ticks 11%, 30 ticks+ 0%
Medium chest armor only (30% drop chance per tick): 1 tick with no drops 70%, 10 ticks 3%, 30 ticks+ 0%
Heavy chest armor or light vitals only (40% drop chance per tick): 1 tick with no drops 60%, 10 ticks 1%, 30 ticks+ 0%
Medium vitals only (60% drop chance per tick): 1 tick with no drops 40%, 10 ticks+ 0%
Full light armor (70% drop chance per tick): 1 tick with no drops 30%, 10 ticks+ 0%
Heavy vitals only (80% drop chance per tick): 1 tick with no drops 20%, 10 ticks+ 0%
Full medium or heavy armor (100% drop chance per tick): always drops immediately
Base drop chance = 10%
Light chest armor only (40% drop chance per tick): 1 tick with no drops 60%, 10 ticks 1%, 30 ticks+ 0%
Medium chest armor only (60% drop chance per tick): 1 tick with no drops 40%, 10 ticks+ 0%
Heavy chest armor or light vitals only (80% drop chance per tick): 1 tick with no drops 20%, 10 ticks+ 0%
Any heavier arrangement always drops immediately
The build in question is between light vitals and medium vitals, so I'm guessing that the base drop chance is maybe around 3%?
In addition to all of the levers identified in the prior post (location multipliers, weight multipliers, base rate), the other lever I can easily see that can be used is changing how frequently checks are made (don't know if that's easy or not, but 3-5 seconds seems like a good check duration based on how long it takes to open a channel and how long it takes to attack without aiming).
