Do Pi expansion first, it really helped me to realize how many loci I have at that moment. I had gone through 100 Pi digits at my very beginning of mnemonics, like 3 years ago. About a year ago, I did the construction of PAOX. Yet, I found myself cannot control such a roar system! So, I did another practice, Memorize the first thousand Pi digits with PAOX. When I did about 400 Pi digits, I gave up using PAOX, Erol suggested to me start from basis, master P->A->O util what I aim at.
Back to the track, why I suggest you memorize the 1000 pi digits first. Not only because it is a decent method to train your number skills but also a great way to find out how many loci you have. When you struggling with how to organize your mp, there is no need to having them be exactly connected in a real-life. Just persuade yourself, you can do teleportation, then between the large gaps of mp, imagine yourself do a time/dimension jump to the next mp is totally fine.
This is for you to check progress.
You might also wonder how to react to a certain digit quicker.
It is always good to embrace learning new mp. I am sure we have got many palace suggestions in this forum. Finally, I suppose for a memory trainer (not an athlete), having 4-digits in a locus, with 30 loci per mp. 600/4=125 loci, 125 / 30 = 4 and round-up for 5 mp is pretty enough for a day.
