Compare the p47M to the p51.
The rules are simple: Don't be a dick.
It was skuzzy's <----- fault.
We just witnessed a miracle and I want you to @#$%^& acknowledge it!
Look at what the most used fighters are. That is why the P-51D has an ENY of 5.
ENY not generated by a single criterion. It's by taking everything into account... pure performance, versatility, usage and so on.
The 109K should be 5 with the P-51 and P-47. Sh*t, make everything have a ENY of 5.
