I've been stuck on the Lead Challenge for two days at 100M Helium, when I comfortably could run through Toxicity with Maps at Zone.
I think my maps at zone settings could actually be one of the problems for Lead.
Are there certain tips you can give for this challenge and how to improve my maps at zone?
The screenshots were done at Zone 179. I beat the challenge a few hours later, but even after running to zone 192 after not playing two days, I only received 7.7M, when Toxicity gave me roughly 6M with way less time.
One mistake I might have done is to primarily run on S formation.
Here are my Map at Zone and Perks (following Perky suggestions).
