There are only two sounds that matter when I place an order. And the time in between.
The “ping” of the PayPal confirmation that money has been transferred, and the “dingdong” of the doorbell.
On average the times of Neal are not spectacular faster or slower than the times of the big sellers.
And don’t forget: Neal is practically a one-man-band. IMHO he is doing a dang good job! 
You want it yesterday? Not for those prices. You know the rule: want it good, fast and cheap? Pick any two.
Relax, and be surprised when the doorbell rings. I have a spreadsheet that says: in the end it always rings.
