Spend less time getting into your accelerative learning state. It sounds like you're trying too
hard.
The idea is to get relaxed about it... do the same thing that you do for flipping for making your mental note of your purpose once done get into photofocus and start flipping the pages.
Say the chant nice and even relax is a good word to say over and over as you flip the pages if you cannot remember the chant.
In all get from your purpose to ALS tp photoreading in about 90 seconds or less. So do that with the same sense of play you use for the photoreading stage alone and you will find it works just fine.
Also drink plenty of water just before photoreading this helps to avoid headaches.
