Are you wanting to do regular raids or Dynamax Adventures specifically?
For DA there's basically no barrier to entry, you can go to the Crown Tundra very early in the SwSh(like 1st or 2nd gym), get some Lvl 65 mons from there and rofl stomp the main game.
You have to get to the 6th gym to get the shiny charm, so if you import a living dex then your DA shiny odds becomes 1/100. My average hunt for a shiny legendary is around 70 captures/successful raids though some have gone to 150 captures.(Dialga)

Last run of the night, had a beer, took a break outside to puff a cigar, was falling asleep on the couch.
The week long hunt ends at 147 runs. Hope you anons have good luck too.
