Biggest thing for me is your #5. When I watch others cook I see a lot of downtime. 30 seconds here waiting for oil in pan to get hot, 30 seconds there chatting with me while their water boils, it adds up to minutes and minutes that could have been spent washing dishes and cleaning surfaces. For me the perfect cook is when the last thing comes off the heat it's the only dirty dish, I can plate it, wash the dish in the sink, then leave the kitchen with the food and the kitchen cleaner than when I went in.
1. There is no "mis" for hello fresh recipes, literally everything is presented in a bag to you. There's often no measuring or any dependencies other than oil, salt, and pepper.
2. cleaning while you cook is not a time saver for producing the food, only a time saver when considering overall time in the kitchen.
In my experience with meal kits over the last two years, the biggest time savers are nothing like what you said.
1. Meal kits try hard to not use multiple pans, as not all kitchens have that. Parallelize cooking where possible.
2. Parallelize chopping with cooking by getting some help.
3. Pre heat your oven before actively starting cooking in the kitchen, ie don't stand idle.
Even still the recipe times are incredibly optimistic.
