For me, I cleared it with speed ranging from 378 - 478. I even had to remove Orchid for this map (because of the insane speed, whichever team she's in will pretty much breeze through the map, the webs can only slow her for like one turn).
And yea, the only thing you can control here is that node containing the blue arrow where you either go right (to the middle circle) or go further down. Rest is pure rng.

Then again tweaking team speed will help A LOT, especially when one or two teams will end up going to the webs right away.

Side note: for team power, my weakest team was around 42k. They didn't have any problems.

Finished!

Got super lucky -- all five teams stayed in the big center loop instead of going to the top-most boss right away. Rearranging the teams helped, too. Teams 1 and 3 were around 350 speed; teams 2 and 4 had around 550.

Done as well, finally. Back to 12-3 i go.

While my main account finished the event due to pure luck and RNG, my alt still has 11 medals due to RNG. Though I did roll the 10+1 gacha on my alt. and somehow got 3 copies of Saffron Tulip (wut?), as well as Lilac (new girl), Cyani, Hinoki, and another St. Paulia. Lilac will probably help me a lot for the second phase. And my Saffron Tulip now has 4 equipment slot, so go RNGesus. Time to continue doing the ?-4 mission and hopefully I get the 3rd medal.
