Estimated Time from First Contact to Phone Number

I'm not one to pick up phone numbers from women quickly or easily. Most of my contact with women is online, since I try to date largely within my church--and that is scattered, with women few and far between. So I thought I'd think about women I was interested in whose phone contact information I've gotten and how long it took (the y-axis represents the number of weeks, the x-axis represents the particular woman):

A lot of this delay is my own (note how, in the above, sometimes women ended up giving me the phone number without me asking), but often the women themselves delayed--I asked, but phone numbers weren't in the offing, at least not at the first request. In general, I think I've taken too much time to ask (if I'm interested, I should just move to phone and meeting as soon as possible), but interestingly, even exorbitantly long times of knowing someone have not always yielded a phone number right away.
