Interesting that you chose as your second episode a method representing such a tiny percentage- however, I was delighted as A= I had seen the first episode and I wanted to know B I definitely learnt something totally new !

Radial Velocity- beautifully explained ! However, it went a bit odd at 6 mins with the amusing number of "Four hundred, two thousand and seventy six- and then the statement that 820 is 90% of that figure and the most common method- Am I missing something, 820 is clearly not most of 4 276.

Just my enunciation wasn't clear enough! I said (or tried to say) 19% 😅
