AA'ing give way more then ASW work, even with HH's I'm guessing cause the HH's are
considered torpes by the game, whether it's true or not I'm not sure.

XP gain percentages on sailors based against ship level. Personally I say keep it between
9 levels under ship and 25 levels above. Keeps you at 90-100% full exp gain.

If your under level 20 or so, Premium + games will get him up (the bonus 1000 exp is
enough to move through levels). Outside of that, your going into a lower level ship to
get anywhere. This is why you see people that plan out their crew going through 2 lines.
Thinking of just using the high level crew/ship to level the low doesn't work. Level
them up equal and it works better (keeping in the above level range compared to ship level).

Exp gain is based on several factors. Personal credit gained per battle (Hitting other
ships, AA'ing Planes, etc etc) then there's shared exp in some game modes (GB2 being the
most popular.) Ship level vs Sailor level is a major factor, basic rule of thumb is 5
below and 5 above is optimal exp range for a sailor (For example a level 60 sailor in a
level 103 ship would gain almost 0 exp where as the same sailor in a level 60 ship would
gain 100% exp.) And there's a whole bunch of other factors that we have no real control over.
