Best results on Tier3+raids achieved by anyone?

I think that Rhydon could be done with 2

Even a team of 6 level 39 Mewtwos with Confusion/SB can't solo a Jolteon, though.

I was part of a group of 4 that so, so nearly beat an Articuno. We were 1 or 2 seconds away and the raid ended so we couldn't try again. As I have almost nothing powered past level 30, we can conclude that it must be possible for 4 :-)

I can take >1/3 health off a Lapras, so that's definitely doable with 3 players.

Part of this depends on the Boss's moveset. I can solo Machamp with Close Combat, but not with Dynamic Punch or Heavy Slam. I'm sure that the same thing applies for the most maxed out players, just at another level.

Mine:
Vaporeon- Solo in 2nd day of raids
Gengar- Solo
Alakazam- Solo (2 psycho cut/FB) in 5th day of radis
Arcanine- Solo in first day of raids
Machamp- Solo
Flareon- Tried multiple times; 2 times were 1+ hours sessions, no can do; 3 lvl 39 RT/SE + 1 lvl 37.5 RT/SE - all 15 attack, >=96 IV + lvl 39 HP Vape; Ember/OH, Ember/FT; in another try I managed to yellow and red a FB one in time (91 and 46 seconds), failed at the end, 4rt Golem was smaller then (lvl 30 only). Not able to do similar since :(.
Jolteon- 2 (first solo try :) in first day of raids, first premium pass lost :))))) )

Tier 4:
Venusaur - large group
Blastoise - large group
Charizard - large group
Rhydon - large group
Lapras - 6
Snorlax - 4
Tyranitar - 4 (close in 3, but 3rd one rejoined without revives and did not make it)

Tier 5:
Articuno - large group
Zapdos - 4 easily; tried in 3, very close, the other 2 had Android phones (time lost at start and rejoin).
Moltres - 3 - multiple times. Single I bring him near yellow
Lugia - large group; tried to get a 5 or 6 party, did not managed to get together the right ones

Entei in 3 is next, should be easy to get a party since every high level has maxed on close to max Vapes (unlike Golems; appears that the inertia is big, a lot of high level in my city still spend dust on Dragonites)
- took a bit more then 1/3 today with 4 golems, 2 vapes and Tyra + Rhydon after rejoin (the app did not defaulted to my 3rd big big Vape, preferred multiples of the above and even a Kabutops).
