The thing is that drift isn't determined by the time of flight. It's related to the "delay" time, i.e. the time between when the bullet arrives in a vacuum versus the time that it actually took in air.
The HV round while having a shorter time of flight, has a greater delay...more wind drift.
If you are interested, PM me an e-mail addy, and I can send a reasonably rough "stepwise" spreadsheet .22 model.
