I think it's important to note these approaches aren't one size fits all. What you're saying rings true for me: it's easier to work for 2 hours vs. 1, and the pomodoro method absolutely has not worked for me the few times I've tried. I have friends and coworkers who are the opposite though. Their barrier to the "flow state" is much lower than mine but they seem to fizzle out faster. IMO it's all about experimenting with different approaches and finding blend one is to your taste.
