Highest dps by type page
Answers
DPS means damage per second. A pokémon with a higher attack stat will deal more damage per second if moves are equal. Starmie has a higher attack stat than Vaporeon.
This does not mean that the higher DPS pokémon is better. In this case, Vaporeon is much more tanky than Starmie, so its overall performance is better.
Surely it should be Kingler with Bubble / Water Pulse.
The PPS with STAB of Bubble is also 12.50 (like Water Gun), while the charge move Water Pulse does 2x70 power, more than 1x130 of Hydro Pump (you get 3 more seconds delay with the 2-bar move, but it may be compensated a bit by the slightly higher EPS by Bubble)
The attack stat of Kingler is 240.
I just looked at the Pokémon pages for vaporeon and kingler, and the "true dps" (varies for each Pokémon and their attack stat, I believe) and found th following
Kingler:
Bubble: 15.83
WP: 33.13
Vaporeon:
WG: 14.00
HP: 51.82
Like you said WP requires half of the energy, but its low cooldown time may be the cyclical dps. As well, the difference between the two fast attacks is not huge
Also I wasn't the one that downvoted, this was a good point. Unfortunately kingler currently doesn't have access to hydro pump (I forget if it learns it in the main series)
Yes. For the charge moves, the listed "DPS" is meaningless as such, because for some reason it is calculated only over the move execution time, not the charging+execution cycle.
A 100% energy bar stands for an amount of charging time, depending on the quick move (excluding dodging). A 2-bar charge move fires twice in that time, but will cost twice the execution delays otherwise used for charging, which lowers the actual cycle power per second - but not by the amount suggested by the listed "DPS".
(listed DPS which would only be valid if the charge moves could be fired all the time like quick moves)
If 100% energy takes 12 seconds to charge, and the move duration (cooldown) is 3 seconds and has 150 power, then cycle PPS is 150/(12+3) = 10.
The move of 2x50% takes 12 seconds of charging but with delays of a total of 6 seconds, for 2x75 power: 150/(12+6) = 8.33.
Then the 1 bar move is 20% more powerful, which is not the 50% difference that would be suggested by DPS based on Power/Cooldown.
Furthermore, the charge move execution delays also reduce the number of quick moves that can be executed during the cycle, which reduces its PPS. It is thus best to state the combined cycle PPS of a moveset.
