Looks like a temporary trend of doubles. Looking at OH, since March 26th, there have been only wo doubles, not including the ones you posted above, so this is probably why you have four doubles in a short time.
Personally, I would focus on non-doubles at this point forward for a while. I don't like doubles anyways, so I steer away from them. Doubles show on average about 1 in every 4 draws.
I'm currently working on a better system using the same concept of pyramids, like this system here.The pairs it produces show about 90% of the time. And it only produces nine pairs. But this is a boxed system.
The problem with posting this system is that it depends on a KEY number to be used. That key number is only available to those who have access to the program which tells me what key number to play for mid and eve, and whatever state I choose. The program costs about 10 bucks for a 6 month subscription.
Please don't ask for a link because there is no free advertising at LP. Not even a PM.
But at least you'll have nine pairs to work with, and with a hit rate of about 90%, it should narrow down the picks.
Yesterday for Florida, it predicted the number 1 for mid, and the number 4 for eve. Both were right on target.
Mid was 219, and eve was 834
It doesn't predict correctly every time, but pretty close. It got today's mid incorrect, so it's not perfect, but a good tool to have.
If you want a key number for your state, just ask me in a PM.
