That's not quite what I'm saying.

Compare

set measureAllModels ON
measure (atomno=1 and */1) (atomno=3 and */10)
show measurements

Measurement Information
distance    ?? ??     C 1/1 #1     C 3/1 #3
distance    ?? ??     C 1/1 #1     C 3/2 #3
distance    ?? ??     C 1/1 #1     C 3/3 #3
....
distance    ?? ??     C 1/1 #1     C 3/n #3

for all n frames.

with 

set measureAllModels OFF
measure (atomno=1 and */1) (atomno=3 and */10)
show measurements

Measurement Information
distance    ?? ??     C 1/1 #1     C 3/10 #3
