[Sunrunners_Fire]

Assuming HT 10 and Heavy Exertion ...

Breath Holding 1 [2] ... 20 seconds
Breath Holding 2 [4] ... 40 seconds
Breath Holding 3 [6] ... 80 seconds
Breath Holding 4 [8] ... 160 seconds
Breath Holding 5 [10] ... 320 seconds
Breath Holding 6 [12] ... 640 seconds
Breath Holding 7 [14] ... 1,280 seconds
Breath Holding 8 [16] ... 2,560 seconds
Breath Holding 9 [18] ... 5,120 seconds
Breath Holding 10 [20] ... 10,240 seconds

vs

Doesn't Breathe (Oxygen Storage x25) [10] ... 250 seconds
Doesn't Breathe (Oxygen Storage x50) [12] ... 500 seconds
Doesn't Breathe (Oxygen Storage x100) [14] ... 1,000 seconds
Doesn't Breathe (Oxygen Storage x200) [16] ... 2,000 seconds
Doesn't Breathe (Oxygen Storage x300) [18] ... 3,000 seconds
Doesn't Breathe [20] ... infinite

Both advantages are flagged as Physical and Exotic. If I can buy one, I can buy the other one. "Doesn't Breathe (Oxygen Storage)" includes "Resistant (The Bends) (Rare; Immunity) [5]". Subtracting [5] from Doesn't Breathe's costs for an apples-to-apples comparison:

Doesn't Breathe vs Breath Holding
x25 [5], vs (x4 [4], x8 [6]) ... x25 vs x6 [5]
x50 [7], vs (x8 [6], x16 [8]) ... x50 vs x12 [7]
x100 [9], vs (x16 [8], x32 [10]) ... x100 vs x24 [9]
x200 [11], vs (x32 [10], x64 [12]) ... x200 vs x48 [11]
x300 [13], vs (x64 [12], x128 [14]) ... x300 vs x96 [13]
infinity [15], vs (x128 [14], x256 [16]) ... infinity vs x192 [15]

Assuming I have sufficient points for either, is there any reason I should buy Breath-Holding instead of Doesn't Breathe? Theoretically speaking.

(Just trying to make sure I'm not missing something.)
