Each flyer is different and we all progress at different rates. However, you sound like you're doing very well. I'd say always practice what you know and try to add one new thing once you have the things you know how to do down. Practice that new thing for a while until you are fairly good at it.

For example if you set out to do loops then just do loops. Don't try to confuse yourself by adding rolls in there as well. Once you get your loops down then move on to rolls or stall turns or whatever. You have to build the basics first and get proficient at them. Once you have those basics down it then becomes a matter of putting several of them together and before you know it you have a routine. Jus remeber a that just because you know how to due a stall turn, loop, roll, nose in hover, auto, etc. that you shouldn't keep doing them. You always need to keep practicing everything. That's how you get good and after a time things will start to become second nature to you. That is you'll be able to do a manuever without ever thinkig too hard about it. You just do it.

One last thing; someone once asked Hanno Prettner (world class aerobatic pattern pilot) how he became so good. he said he praticed every day but only for an hour or so. Any more and he would become sloppy and make mistakes. Try not to push yourself too hard. Sometimes if you push too hard then your progress will actually slow.

Good luck and have fun.
