Value input in TAlly

6

I’m still not sure I fully understand the problem, but I do know that Tally doesn’t accept fractions as entries. you have to enter in a decimal number. if you’re worried about rounding errors, Tally’s data appears far more exact than it is. We generally look at the numbers as rough estimates, and that any reductions need to be an order of magnitude +/- to have a potential for actual impact. To give an example - EC3 applies a ~20% uncertainty value to most of their information to account for variations and uncertainty in the EPD data they are pulling in. Tally should probably do the same, but currently doesn’t.
