 Hence, it's worth rethinking the historical opposition to multi-dimensional resource limits and considering them as a pragmatic way to simultaneously achieve moderate scalability gains while retaining security.
 
-Additionally, the stipend mechanism makes the two-dimensional optimization problem even less of an issue in practice. 90% of all transactions ([sample](http://vitalik.ca/files/misc_files/gas_and_calldata_sample.csv) taken from blocks `13500000, 13501000 ... 13529000`) have <300 bytes of calldata. Hence, if a naive transaction selection algorithm overfills the calldata of a block that the proposer is creating, the proposer will still be able to keep adding transactions from 90% of their mempool.
