How do you Practice Memorising Your Memory Palaces?

I am short of palaces right now, I keep using the ones I have over and over.
I’ve been focusing solely on my little system so I’ve not had a chance to create my palaces.

I am trying to create memory palaces for each discipline.

Cards -> 14 Palaces each with 26 locations. Two palaces for each day’s practice
Numbers -> 14 Palaces each with 20 locations. Two palaces for each day’s practice
Binary -> 14 Palaces each with 20 locations. Two palaces for each day’s practice
Words -> 14 Palaces each with 25 locations. Two palaces for each day’s practice
Images -> I don’t use any palace for this discipline. I use my shapes instead.

Apart from this I also want to create palaces for;
Phone numbers & names | Dates | To Do Lists | Main Points in the Books I read.
How would you go about doing this?

I use my own little system which doesn’t require a memory palace for memorising a small piece of data such as a phone number etc, but then I have to place that data into a memory palace to recall at a later date. So I still need a lot of palaces for my daily activities as well.

Im am indecisive to have all the palaces with a fixed number of locations, ie 26 each or 50 each.
But If I’m memorising numbers in Memory League in practice or in competing, I only need 20 locations for 80 digits - using 2 digit system.

How do you organize your palaces for competing, and for personal activities?

How do you practice memorising your memory palaces so you know each of them by heart?

Thank you.

How many palaces do you have for practicing all disciplines?
How many locis in each palace?
