After the PhotoReading step the break should be at least 20-minutes for a book (articles and short text yo can activate immediately)
What to do during your break... Ask a mum I'm sure she'll have plenty of suggestions. Make the bed walk the dog, take out the garbage.
Ask a friend. go surfing, play a video game, go cruisin.
Ask your significant other... Enough said!
Ask a child play a game outside, lay on the ground and watch a bug.
Okay during a 5-minute break from activation. Edu-k. Brain gym.. Get up and make your own coffee. Get a fresh glass of water... walk to the fridge... bathroom break. Listen to a favourite song. Make a quick phone call (if that's humanly possible 
)...
Mostly get away from the study area
The 15-minute break is pretty much the same as the 20-minute break make the bed for the heck of it.
For two books be sure to State your purpose and affrim intent before each book you can do one after the other. You don't need to spend as much time entering the Accelerated Learning State the second, 3rd, 4th or 5th time. After 5 take a break it probably took 20-minutes to do them all.
