Small update: the binary size comparison table is now updated to compare the correct thing – actual code sizes. Previous version contained a bug where we generated correct but uncompressed images with a lot of zeros.

The fixed version shows an even more significant gain of PVM2. Note: [PVM2 is standard RISC-V (+c)](https://forum.polkadot.network/t/risc-v-is-all-you-need/17804). So this really reaffirms our conclusion – **the custom PVM ISA is unnecessary and actually much worse than PVM2 (standard RISC-V)**. PVM2 (standard RISC-V) beats PVM on binary size, and performance is better or equivalent.
