Carry Capacity Modifier - Integers only?

On the 5e OGL sheet, Carry Capacity Modifier only seems to work with integers and drops any fraction. Is this a correct interp on my part? Example: Given a character with str of 10, set variant encumbrance in game and on sheet. This is then STR*5 is max carry weight. Give char 50 pounds of equipment and is not encumbered. Add a single CP and the character is encumbered.  This is correct. Change Capacity Modifier to *2 and the same character becomes encumbered at anything over 100. This is correct. Change Capacity Modifier to *1.5 and character becomes encumbered at any weight over 50lbs. This is incorrect, it should be over  75. Change Capacity Modifier to *2.5 and character becomes encumbered over 100lbs instead of 150. In short, I am trying to get encumbrance to 7.5lbs * STR. I can do this with a negative weight allowance in the equipment list as a bit of a hack, but then the actual weight of equipment isn't showing. So, if I need to do a weight check on a rickety bridge or something, I have to remember to account for the negative weight allowance.

Yeah looking at the code it only uses the first digit. So you are correct. But, it does also accepts a "+" symbol or a "-" symbol. And doing this basically increases or decreases your strength score when calculating encumbrance. So in your example if you have a player with a STR of 10 and make the Carry Capacity Modifier a "+5" then his capacity will be 15*5 (instead of 10*5). Which would be 75lbs. Heavy encumbrance would be 15*10 (instead of 10*10). Which would be 150lbs. So the math works out to what you're looking for I think if you do that, but feel free to fiddle with it and let me know.

thanks for the feedback and confirmation. Adding 5 to STR modifier works at STR 10 but not at other weights. For example, STR 15 with my custom 7.5 weight is 15*7.5=112.5.  If I add use your method I get (15+5)*5 = 100. To make it correct, I would have to add 7.5 to the STR. That means adjusting each time a player increases STR and it brings fractions back into the equation.

I kinda figured the math wouldn't be perfect but it was worth a try to get it close. Your other option as a Pro member is to take the roll20 character sheet and customize it. I've never tried making a custom character sheet but if you want to go down that route let me know and I'll be happy to show you were you would need to make changes.

Thanks. I don't think I want to go down the route of custom char sheets just yet.
