Did I miss your EASY sample or you add it later?
I also think like Sara that you have a case of UT or OT, I'm just not quite sure which one it is from looking at your EASY.
You need to get the A time right, and yes it's not easy, but it's possible. I can tell what I did now because I had the same situation (not with the crying, but 40min naps after a long time we didn't have them):
The first A time of the day I knew but I had to figure out the second one, so I gave him the 5min more of A time than I gave in the morning (the first A time is usually shorter than the next one/ones). Every two days I would up the second A time with 5min until I got to the right one. I was lucky that it took me only four days, but I was willing to go as long as needed. You could do the same also for the first A time of the day till you find what is right for you. I would however wait until you finish with the GS, I found that it's very hard to establish anything new while they in the middle of it.
