I wouldn't pay any attention to what others are playing or posting unless they are known as someone who wins a lot and I don't know of any such person. If I can't think of any numbers to play on my own, I don't play.
It's so strange you mention this. I knew a friend by the name Rob a few years ago, and told me of a story about one incident while standing in line at a store in Ohio. The guy in front of him bought 50 p-4 straight tickets, I forget the numbers but I think they were 4396, but he won the next day.
My friend Rob Didn't play the numbers, and to this day he kicks himself.
I say "maybe". P3 & p4, there is no disadvantage; but for p5 & up, you're really getting a thin slice there. You'd have to go dollar-for-dollar with the other guy just to get 1/2 the top payout (in most states). For the p5+ games, I would only do so if the number was already on my list.
