What can I make the most out of this?

I just spawned Elder on Red Maps.



Guardians occupied 2 T13, 1 T14, and 1 T15. While Elder is on T14.

I need 11th to 15th memory fragments. What sequence should I do to get most memory fragment out of my setup?

EDIT:
I was asking because I saw this in the wiki https://pathofexile.gamepedia.com/Memory_Fragment, and also read some post in reddit about memory fragments

You can get the 14th at least, just open the t14 map with a character, then relog to another character and clear the map + boss. Repeat until you have all the fragments. For the 15th though, I believe you might have to have Elder on a t15, and not a guardian, but you will find out when you get there.

T14 with elder or T14 with guardian?

The last memory frag (#15 out 15) only comes from t15 elder so you should be able to get #14 mem frag with what you have there..

is this possible ?
