Formula for Battleship Endurance: [(Skill Level * 4000)] + [(Character Level - 120) * 2000]

Endurance at Level 124 (earliest possible level to max Battleship), 150 and 200.

Level 124:
01 - 12000
02 - 16000
03 - 20000
04 - 24000
05 - 28000
06 - 32000
07 - 36000
08 - 40000
09 - 44000
10 - 48000

Level 150:
01 - 64000
02 - 68000
03 - 72000
04 - 76000
05 - 80000
06 - 84000
07 - 88000
08 - 92000
09 - 96000
10 - 100000

Level 200:
01 - 164000
02 - 168000
03 - 172000
04 - 176000
05 - 180000
06 - 184000
07 - 188000
08 - 192000
09 - 196000
10 - 200000

Conclusions:

• If the information blitzkrieg posted is correct then level 10 Battleship isn't worth it past level 124.
  
• At level 124, level 1 and level 10 are proportional in endurance:cooldown ratio.
  
• Every level beyond level 124, level 1 Battleship is the best in terms of endurance:cooldown ratio. In fact, at level 200, level 1 Battleship is over 3 times better than level 10 in terms of endurance:cooldown ratio.
  

Someone please explain to me why the cooldown is even related to the durability. If you can take significantly more hits on a higher leveled battleship (the def added is brought into play as well), then wouldn't your ship last longer even though the cooldown is longer?

Also, if you aren't forcefully dismounted from your battleship before your cooldown ends, then doesn't that mean you can literally stay on your ship... forever?
