"Is the Go Plus the best choice for exp grinding?"

#PokemonGO: The Go Plus allows you to throw a single regular red ball at any pokemon, you either catch it for 100XP or it flees for 25XP.You don't have to keep throwing balls until it flees to get your 25XP, you get a minimum of 25XP for each ball. At a 50% flee rate, that's an average of 62.5 XP per ball.If I applied some armchair math, you could grind to level 40 with at most 20,000,000 / 62.5 = 320,000 red balls.That's 320,000 / 200 packs of balls from the store at 800 coins each, coming to 1,280,000 coins.That's 1,280,000 / 14,500 coin purchases at $99 each, so you could grind to level 40 for at most $8,739.31!I believe this is an upper limit, which can probably be revised down due to free pokestop exp, lucky egg evolutions, walking eggs at the same time and pokedex exp. I'll leave the proof to the reader :)Edit: mathEdit2: thanks to /u/FakeKitten for pointing out level 40 only requires 20,000,000 exp via /r/TheSilphRoad http://ift.tt/2iEAote
