how does a large brew impact recipes?

Just starting out with pourovers after having gone from drip to Moka Pot to AeroPress. I just purchased a Switch which I'll use with my K7 grinder and play with pourover, immersion, and hybrid. I notice most/all recipes are for about 250ml or less. If you wanted to brew a double batch at once would it impact the recipe significantly? I could see it having an impact on the bloom and drawdown times but I wondered if there was some sort of rule of thumb?
