Why is integration time and SNR so weird? Part I.

Dr. Detail has been bothering me for a while about some SNR claims. Basically, some people in forums and in videos are claiming that 4x the signal only doubles speed. But is that true?

What was that, Dr. Detail? Huh? Something about the video not giving the full picture? Huh. Well, I guess this is just part I. Stay tuned!
