P4(x) against e^x
connecting
The degree-4 Taylor polynomial the chain multiplies the floor by, against the exponential it approximates. Above x of about 2 the fee grows like x⁴/24, a polynomial, not an exponential.
- P4, what the chain uses
- e^x
Log scale. Above x ≈ 2 the fee grows like x⁴/24, a polynomial, not an exponential.
