I've been using TIPP 10 typing(https://www.tipp10.com/en/) for most of my practice. I'll go through the training lessons and open lessons. I usually practice about twice a week but am actively typing throughout the week as well. I almost feel like I am trying to type too fast and maybe that is the cause of my issue on accuracy. I'm also not sure I like how 10fastfingers works, they don't include punctuation in their practice modes and give you a higher wpm minute than something like typeracer.

How much is "twice as many mistakes"?  That's important!

The prevailing wisdom is that accuracy should be 98% at minimum.  Type slower if needed.

I realise this thread is a bit dusty, but I can tell you when I switched to Dvorak many years ago, I hit a plateau around 60-70 wpm that I wasn't able to overcome until around my 1 year mark.  I eventually hit ~100 wpm, but it took a lot longer than I was expecting. 

If I was you, I would definitely stick with it.  It may be frustrating now, but you'll get over the hump.  Just keep practicing and set some goals for yourself.
