"Oh, sure. I once had a kid take the knife from me and kill me with it--but I took his chain from him, and killed him with it, and then I also had the chain. I'm fine, really. I'm not built for that kind of fighting."
Derek is, incidentally, a particularly unathletic looking overweight kid.
You are correct that the backpack does not count if you are wearing it when you verse out. However, since you have now made an issue out of the backpack, I have to check on it.
You have a 1@9 strength. That means you can carry up to 19 pounds "unencumbered", without it having any effect on you whatsoever. That includes all clothing, weapons, and equipment however carried.
Above 19 pounds up to 38 pounds you are "encumbered". At these levels, movement is reduced to half the rate as "unencumbered", and all more complex bod skills are impeded by a -20 sit-mod. Also, stamina checks must be made to continue after a number of minutes equal to your decimalized stamina times your stamina level--for you, you are resting every eighteen minutes while you wear that.
Your maximum "I can carry this" weight is twice that, 76 pounds, listed as "maximum". When you are above 38 but not above 76 pounds, you are prevented from performing body skills beyond the most basic, are slowed to one fourth your normal velocity in all bod movement skills, and you must make regular stamina checks to continue beyond a number of minutes equal to your decimalized stamina--again, for you, every eighteen minutes.
You can lift up to 76 pounds without a check; there is no danger that you would not lift it or that you would hurt yourself. Above that to twice that, you can lift up to 152 pounds on a successful simple (2d20) check, which can be bonused if you are on the low end, and twice again as much, 304 pounds, on a successful difficult (d30+10) check. The simple check weight allows you to move short distances--a few steps. The difficult check weight assumes a serious rush of adrenaline in an emergency situation, such as lifting one end of a car off someone you know, and very little movement in the process.
We can say that you are carrying a pack of 76 pounds as part of a strength/stamina training program. Such a training program would increase your strength and stamina by one intensity in two hundred days. That increase would raise your weight limits to 20# unencumbered, 40# encumbered, 80# maximum, 160# simple check, 320# difficult check. I would also say that the program you've described is double doubled. That means it will be quite exhausting for you now, but will continue to push you (after another 200 days) into the 2@1 range. At 2@1 you gain a "normal encumbrance" category between "unencumbered" and "encumbered", for which Movement is reduced to 3/4 normal, complex bod skills suffer a penalty of -10, and stamina checks are not required. The unencumbered weight limit for a 2@1 strength jumps to 42 pounds, 84# for normal, 168# for encumbered, 336# maximum, 672# simple check, 1344# difficult check. It really does make a difference crossing the level barrier, which is why it is so hard to do.
So trim your "on person" gear to 76# or stop walking.
I'm only strict about encumbrance when players make it an issue. If you want the benefits of carrying around more than you can carry, you pay the detriments as well.
You have not seen any concealed weapons. Of course, if you could see them, they would not be very well concealed....
