That list is lacking P47s speed updates.
After 1.08 patch 6 where P-47D-30 bug was fixed ("Fixed a bug with the P-47D-30 that was causing it to not get its full WEP performance"), I tested P-47s speeds again:
These are the correct P47s speeds for current version.
btw I recall 262 is impossible to test accurately due the fact that auto speed command doesn't support those (IAS) speeds 262 is able to pull.
