With the new version of Cookie Clicker v 2, the Neverclick route has changed completely. It is now possible to get sub 30, maybe even sub 25.
Firstly, the Buildings are worth more, and cheaper. Secondly, the Grandma + Farm Combo is now a thing. Buy 15 Farms, and many Grandmas and buy all their upgrades, when you buy a grandma, it upgrades the worth of a Farm. You get 2 for 1. Thirdly, you can use the Efficient Mine combo, getting the mine upgrade and doubling what the most expensive upgrade you can afford to get in under 2 buys of a mine.
This category is advancing, and everyone should try it out. It's loads of fun.
Update: Efficient Mine isn't very good, as most the run you'll just be waiting for 600,000 cookies.
SRC has come up with an IRL section. All IRL cooking backing speedruns will commence there moving forward. Please follow the boards if you're interested in IRL cookie backing speedruns.
