If there’s really no upper limit to feruchemy for practical reasons* , why didn’t Sazed just fill steel at ridiculous levels for a few minutes in WoA, and then go back to running instead of leaving his steelminds there?Say, being some 100,000 times slower than he would normally be for about a minute. Meaning that a feruchemist should be able to fill a given metalmind in very short periods of time if you fill at a high enough rate.
The low end is bounded. You can pull out tons–but in filling, you can only go so far. I didn’t ever explicitly talk about this in the series, but the implications are there. Not all have the same bounds, but in your example, the body just can’t slow beyond a certain point. Think of it this way–you can only fill a weight metalmind with as much weight as you have to give. So you can become very, very light–but you only add to a time for doubling your weight. You can’t make yourself 100,000 times slower and gain 100,000 times multiplication. You can give up all of your normal speed, and so when you tap that speed out you are at 200% for an equal period. (And that’s a theoretical maximum; realistically, you can only go to down around 75% slower or the like.)
