>>40234379It holds up pretty well though. At least for a certain age range.
12/2 plus 7 is... 13? You can only date people older than you? Formula doesn't work yet
13 comes out to 13, 14 to 14. Formula still broken.
15/2 plus 7 is 14, formula technically works but might be too strict (15/13 is probably okay)
16/2 plus 7 is 15. Maybe too strict, 14 might also be alright.
17 = 15. Seems about right.
18 = 16. Close enough; 18/15 might also be fine.
19 = 16. Sounds right.
20 = 17. Reasonable.
21 = 18. Pretty accurate.
22 = 18. No problems there.
23 = 18. Sure.
24 = 19, okay
25 = 19, accepts an age gap that many would condemn in common day
26 = 20, reasonable
So the formula works well for 17 to 26. It falls apart after that due to both sides being adults.
