Overall? Maybe? Will I book that executive class hotel within walking distance of my venues instead of La Quinta? Yes. Will I book that better plane ticket instead of cattle class? Yup. etc. Those are probably in the range of about a factor fo 4x-5x. This also holds a little better if I talk about lab equipment. I have wasted a lot of time trying to do measurements with $100-ish pieces of equipment when I should have bought the $10K piece of lab-grade equipment that I then use for other projects as well. Now I try to optimize that better.
