Oh, and I think you asked somewhere how to know when they are done? There's no easy answer except that you can kind of tell, but it's also just a matter of sort of "testing" when you think they are. Each dog is different in how long their ears take, and it isn't necessarily a matter of how long the crop is. We generally recommend to wait through teething, because it's safer. You can kind of get a sense of how firm the ears look as you are changing posts. If you start to think they really look strong, maybe you leave them down an hour between posts instead of putting them right back up and see if they look any softer. Maybe the next post change if they still seem really firm, you try two hours. But again, this is if you truly think they are standing well. Since you got started a bit late I would personally probably post a bit longer before "testing" because I'd really want to be sure, but that's me.
For reference, Richter's ears were done fairly early - it's been a decade, so I can't really remember, but probably around 7 months, maybe? Sypha's ears took much longer...I was posting one ear until she was a year old, the other ear was done maybe a month earlier. Leon's ears are doing quite well - I'm shocked at how quickly they seem to be finishing up. He was six months this week. I'm leaving them down today to see how they are doing all day ...last week they were down all day with his post change as well and were looking great. I think they are very close if not done.
