Encumbrance has always been a painful thing. And it only gets more diabolical with house rules that "fiddle" the weight of coins and armor...
So. Let's assume a regular man-type can carry up to 100 lb at 9", and up to 150 lb at movement rate 6". An unusually "strong" man (15+ strength) can instead bear 120 lb and 200 lb at those movement rates.
DD5 has 100 coins weighing 5 lbs (half the load of M&M, so you can carry twice as many).
The jewelry, cups, bowls, etc. can weigh an average of 1 lb each; there are 12 pieces, so that's 12 lbs.
Leudigar's sheet says he is carrying 99 lb.
Zem's sheet accounts for 60 lb of gear, plus he appears to have some other stuff. Let's round it to 70 lb.
Manfried's sheet doesn't appear to have a load, but a quick scan looks like it's around 40 lb.
Karl's sheet doesn't appear to have a load, but a quick scan looks like it might be around 70 lb.
If you want to figure a more accurate load, or to drop some stuff,
please update the gear and loads on your sheet according to p18
here, except that armor weighs 20/35/50 lb for leather/mail/plate (or 15/25/40 lb for dwarfs).
Assuming you want to maintain a
9" move rate, then it appears that Leudigar is full, Zem can carry another 20 lb of treasure, Manfried can carry 30 lb of treasure, and Karl can carry 50 lb of treasure. All up that would be approximately 100 lb of treasure total, or about 2,000 coins. About one-third of what is present.
If you are prepared to drop to a
6" move rate, then Leudigar can carry an extra 50 lb, Zem can carry another 70 lb, Manfried can carry another 80 lb, and Karl can carry another 100 lb of treasure. All up that would be about 300 lb of treasure, or about 6,000 coins. That would be most of what is present. But, remember it was a three day hike to get to here... it could be longer if you're slowed down.
So... what move rate do you want? And what if any gear to you want to abandon?
