@Egger - If the longest phaser strip is the most powerful, we would see the dorsal saucer phaser strip used more exclusively, particularly in scenarios where they were firing to destroy an enemy ship. Instead we get:
- E-D attacking a Husnock ship - used saucer ventral phaser strip and torpedoes.
- Odyssey attacking Jem'hedar ships - used saucer ventral phaser strip.
- E-D attacking Borg ship - saucer dorsal phaser strip + 2 warp pylon point emitters.
- In the DS9 space battles, we don't see the Galaxy-class ships adjusting their attitude to bring the dorsal phaser array to bear and it's pretty much whatever is in the firing arc.
- Also in "A Matter of Time" when they discharged all their EPS taps through the phasers they fired through the 2nd longest strip, the saucer ventral, instead of the longest one (saucer dorsal) which also was in the firing arc.
For comparison, the phaser strip lengths of the Galaxy-class using the Saucer Dorsal as baseline:
Saucer Dorsal Strip Length 100%
Saucer Ventral Strip Length 77%
Secondary Hull Ventral Strip Length 11%
Warp Pylons Lateral Strip Length 5% each
Small Strips 2% each
Personally, I think it's just redundancy. From "The Nth Degree" it would seem that they only need 40 phaser emitters to channel maximum phaser power so any extra emitters on that strip is just for redundancy and/or firing arc.
