Here's an easy PPS pattern: J1 is juggling everything on single spins, J2 on
doubles - even the uncrossing selfs. The passes from J1 are tramline singles
and those from J2 are diagonal doubles.
We can see that J1 is juggling a regular 6 clubs PPS while J2 is juggling a PPS inspired by the 8 clubs patterns made out of 4 clubs solo. The average of all this is indeed 7.
7 clubs, PPS doubles vs singles : <3p
3p 3 | 4p 4 4p>
