Nice! Thanks for sharing and nice write-up.
Funny thing, I've actually been finishing up a little prestige work of my own today.
Important note, though - I exclude any Pokemon w/ max (lvl 30) CP under 1300....including Chansey.
1 - Chansey throws off all of the %'s b/c it's by far the most 'efficient' prestiger. Howeeevverr....
2 - These efficiency calculations don't calculate the chance of you timing out. The majority of times you use Chansey you're going to have a tough time winning within the time limit.
3 - Chansey is super rare. I've caught 23,000 Pokemon and I've seen 8 Chansey - only one with Pound...and obviously not Hyper Beam. The odds that you caught a Chansey with the perfect moveset AND powered it up to the right CP, are slim.
...
As far as max CP goes, I'm not sure about your area but > 95% of the time I'm looking for Mons in the 1200-1500 range...and I can't count on finding that perfect lvl 30 Slowpoke/Abra/whatever with the right moveset
So I'm just trying to keep things as 'real-world' as possible
....
I was doing all sorts of calculations but then realized, you literally only need 3 Pokemon/movesets to cover almost 100% of prestige situations. (The rankings are a composite of the different defensive movesets weighted for strength/frequency)
1) Wigglytuff - Pound/Hyper Beam
What a beast. By far the best overall prestiger.
- vs. Gyarados - #1
Barely beats out Electrode when considering Dragon Pulse/Twister as charge moves (resists Dragon attacks) - He's #1 vs. both of them and #5 or 6 vs. HP - vs. Lapras - #1 (Tie)
Basically a tie with Tentacruel w/ Jab/Sludge. While it is slightly less effective vs. both Ice Beam/Blizzard, it is more effective vs. Dragon Pulse...AND Wiggles does a whopping 20% more DPS. So to me, he takes the win - vs. Snorlax - #1
Without any doubt the most effecient prestiger to use vs. any Snorlax. Hypno is a bit more efficient vs. ZH Snorlaxes (by ~5%) but is way worse (~30%) vs. Lick. Also, does about 25% more DPS. So...yeah. The best
2) Parasect - BB/Solar
- vs. Rhydon - #1
Surprisingly, not only more resilient than water/grass types (b/c of Ground type resistance) but ALSO the highest DPS. The clear favorite - vs. Vaporeon - #4
Second only to a 3-way tie between Venusaur/Ivysaur/Tangela w/ Whip/Solar...however while it's 4% less efficient, Parasect does 6% more DPS. So it's hanging right in there.
3) Dewgong - FB/Blizz
- vs. Dragonite - #1
Don't really need to explain this one. I can usually beat 2 Dragonites twice my CP with sloppy dodging - vs. Exeggutor - #4
Behind only 2 Butterfree Movesets and 1 Parasect. Bugs are the clear winner here, but a) how often do you see Egg anymore....and b) when else are you going to use the bug 'mons? Exactly
Between those 3 Pokemon/movesets alone, you have top 5 prestigers vs. 95+% of Defenders you're going to see!!
Dragonite
Snorlax
Lapras
Gyarados
Rhydon
Vaporeon
Exeggutor
