I've set a Trigger like :

{TRIGGER.VALUE}=0&{testtest:icmp.avg(#10)}>3|{TRIGGER.VALUE}

=1&

{testtest:icmp.avg(#10)}

#0
but it dose not get 10th most recent value exactly and it get 11th value.

for testing it, I set a calculated item by the Formula of "avg("icmp",#10)" but it show the true 10th most recent value truly
