Is my farm working? 2Pb dry farm

[dougsop]

I have over 23,000 plots farming and been constantly getting drop close to the ETW suggested, 2-3 days.
Since the 2nd of May the farm been dry and nothing dropped.
I'm just paranoid that something is wrong, I have checked all the below;
Plots are passing through filters
Response time is < 1s. there are the occasion spike once or twice a day but i think thats just normal.
The unit is fully Sync all the time.
currently running 1.3.5
Done plots check with power shell n30 average score is 1.

Am i just having a really bad luck run or is there something else I need to check ?
