I don't think I fully agree with this. I think most people are quite bad at dating, I know I was. 1-2 per year for me would mean too much pressure. If I'm taking nothing else from using dating apps for the last 10 years, it's that I feel calm and have a good handle on my feelings in those situations, when good people come along I have a much better shot with them now. Obviously 2 good dates > loads of average ones, but the average ones aren't pointless either.
