Gents,
No, PQR using P1G1 to P1G1 did not qualify P1G1 to P1G2
but PQR using P1G1 to P1G2 qualify P1G1 to P1G1, P1G2 to P1G2 and P1G1 to P1G2.
Again, for example two PQRs using PIG1 to P1G1 and P1G2 to P1G2 qualify P1G1 to P1G2 as long as both essential and supplementary essential variables of the both PQRs are the same.
