Question isn’t confusing, it really just depends on what you can handle and what works for you.
2 titles every other day is harder because you need to process more in a single day. But that is the standard listening instructions.
2 titles skipping a day.
Title 1
Rest
Title 2
Rest
Ect
Is easier because it gives more processing time between titles.
The sweet spot is when you find the level where you are being challenged but not overwhelmed.
So the answer depends on the person and the stack and their goals.
I’ve used both strategies at different times, both with success.
So the real question is what gives you the least recon and the most results.
For most people they will get less recon and therefore better results by skipping a day and running a single title each day.
However, sometimes it’s not a problem and you can handle it, so you do it the regular way.
Right now I’m running two titles on the same day. No recon, good results, so there is no reason for me to take it easy because I’m already in my sweet spot for this stack.
The point that a lot of people miss here is that you’re trying to balance challenging yourself with what you can actually handle.
