^ that's a good video until about 3:20 ... not sure why he's angling it back and forth like he's going down a rocky hill on a bicycle though and he wobbles the glass around when he's pulling the point like a shaking lamb's tail. Obviously a tube rest is a foreign country, even a couple of long, bent, nails in the top of your bench to rest the tube in between is better than the wobblies.
If you need more material in your point, just holding it at an angle and moving the glass through the flame in a perpendicular fashion, if you need to move it at all or turning it further out where the flame is broader, rather than angling it back and forth, will give you a more even result. Also, if you learn to pull your points long enough so you can have a point on either side of your working glass it's a lot more useful and you don't have to attach punties etc. I know it's difficult to judge the good information from the not-so-good in a youtube video for someone starting out.
The info about heating up the shoulder to correct an off point is good though. You do this because the point gets thin quite quickly and the shoulder is thicker, so the splash heat, which is gentler, is enough to heat the point in exactly the right place and you can straighten it out easily and with control. If you heat where the glass gets thinner, things can get out of control really quickly.
If I was in SW Florida I'd say come around, I'm a big believer in points and in my eyes it stands in your good stead that you desire to learn this technique. I pull points all day long every day so it would be be no hassle. It's often a lot easier seeing something done and having Zen and the Art of Lampworking explained to you in person. Alas, I'm a little further afield than FL. Good luck on your quest, I hope you find an accommodating lamper down there!
Once you have all the right info, then do what the other guys said .... do the four P's ... Practice Practice Practice Persevere
