-This crate is ~10 times faster than [`hex`] in encoding, and 30+ times faster
-than `libstd` in formatting.
+This crate is 5 to 20 times faster than [`hex`] in encoding and decoding, and
+30+ times faster than `libstd` in formatting.
 
-You can run the following benchmarks with `cargo bench` on a nightly compiler.
