Efficient ways to generare XP during the event

Let's say that you can catch a mon per minute downtown and you sometimes get first throw, sometimes great/excellent throw and always curve, you could probably make a base of 150xp per mon. Multiply by 4 for event and lucky egg, that is 600xp per mon times 30 minutes, which would net you 18000xp. Then add some egg hatches and you should easily clear 20k. Still nothing when a lucky egg mass evolve for 30 minutes during this event should easily net you 150k.

My personal favoured method is doing a lucky egg mass evolve, while catching mon with my go plus at the same time and walking at a frantic speed hatching collected 10k eggs. I have been doing that every saturday when I have my 7 day bonuses. Usually nets me something like 100k.

I think the people who have grinded for max EXP find a loop of like 10 pokestops, lure them all up, walk EXTREMELY fast in the loop and catch, hatch, evolve, with 9 incubators and repeat every 30 minutes under a lucky egg...

That's the fastest way to get to 40. Some in Tokyo find 9 Pokestops and lure them all up and catch non-stop and evolve at the same time...they have unlimited resources to catch due to the 9 pokestops.

Taking down gyms is slow because of the constant healing, running out of healing items, phone crashes, gym lockouts when battling with multiple people, etc...

Nothing beats evolution parties, but you need the mons and candies and that's why hardcore levelers tend to not be that gym focused since it's a slow slow way to EXP (no candies, takes resources, etc...). If you can build a bubblestrat tower with 10 mons, yeah, you can get exp much much faster, but you'd need 10 friends or cheat to get the 10 bubble defenders...

About half the time I can get 840 Exp per catch. This includes a bonus for first throw, Great! throw, and curveball. If it is a pidgey I immediately evolve it and transfer, this gives me 2840 XP!

OK, so for me it was mass evolve yesterday. I, as not many others saved my candy, and evolved just 3 squirtle (2 of them evolved again, both blasts got bite/flash cannon :)) then 12 candies-evolves to finish with my lucky egg of which I bought 50 for my gym coins. 140k from this and still have plenty evolves waiting. Today used another LE to get 50k from spinning/grinding. This 50k was what I needed to level up.
Anyway take your Lucky Egg and strive for a great or excellent throw, you get 840 and 1040 XP respectively for just 1 mon.

I had some candies saved up before the event. Walked with lucky egg. Caught everything, saved it if there was more around, otherwise directly evolving the catches to save time. In transport stretches I kept evolving those saved before. 9 incubators and occasional incense. When I came home I made one mass evolve of those I had not had time to evolve during the walk. Total 500K, 4 hours walk + 30min mass evolve.
