Oversized Evaporator Coil

Hi, all! Back in the day, it was common practice here in the South to oversize the R-22 evap coil by a half ton for more cooling efficiency. Does this oversizing by one-half ton still apply with the newer split systems and newer refrigerants?

Thanks, Mark. But, from what I hear from the majority of the contractors on the HVAC forums, it voids the manufacturer's warranty in most cases to mismatch the coils. I contacted Carrier to ask them directly, but they haven't gotten back to me.
