It's logarithmic in benchmark scores, not in utility. Linear differences in benchmarks at the margin don't translate to linear differences in utility. A model that's 99% accurate is very different in utility space to a model that's 98% accurate.
Yes, it seems like capability is logarithmic wrt compute but utility (in different applications) is exponential (or rather s-shaped) with capability again
Not really since both give you wrong output that you need to design a system to account for(or deal with). The only percentage that would change the utility would be 100% accurate.
