Not necessarily, but it helps aid in my decision making. For example, let's say I have two girls who want to meet on the same day. Which one do I choose to meet? If it is possible to meet both on the same day and the first date starts to cross over into the time of the second date, do I let it run over and flake on the second date, or do I rush to meet that second date at all costs? Date seems to be going well, but based on the past with similar girls, do I go for the one night stand because I know that the chances of a second date are low due to socio-economics/cultural background?
These are all situations that I have come across. I once bailed early on a first date to meet my second date of the night, although the first date would have been much more likely to go on a second date with me. There are girls where the first date went very well, but there was no second date. When I was younger, I had a lot of one night stands with girls from a different cultural or socio-economic background because that is what I went for. A lot of those girls were only interested in sex with me.
If there is no correlation between drinks or dinner and getting a second date, then I can ditch dinner altogether and save a ton of money. If the type and number of venues I go to has no correlation between whether or not I get a second date, then I can go to the local dive bar down the street instead of the fancy bar(s) downtown and save time and money. If there is no correlation between the attractiveness of the girl and whether or not there is a second date, then it gives me peace of mind and makes me feel much more comfortable during the date, no matter how attractive the girl is.
There is a Ted Talk about a woman who did something similar and drastically turned her luck around in online dating by doing so:
