Long delays

I noticed on TRF today that Aerotech actually has three delays certified for the E20W: 4, 7, and 10 seconds. However, where they're for sale, I've only seen the -4 and -7 motors.

I've noticed this before with certain reloadable motors. There are often three delays listed on the packaging - short, medium, and long - but only the short and medium delays are certified and available. This includes most of their 24/40 loads plus a few others:

24mm:
D9-10
D15-10
E11-5*
E18-10
E28-10
F24-10
F39-12

29mm:
E16-10
E23-11
F22-10

However, a number do have long delays available:
18mm: D13-10 and D24-10

24mm: F12-5*, F35-11

29mm:
F40-10
F52-11
G53-10
G64-10
G71-10
G76-10

* The weird ones are the E11 and F12. Both are long-burn Black Jack motors. The E11-3 is widely available, but the listed E11-5 is not certified, and there's no true long delay at all. The F12-3 (certified as -2) and F12-5 are both available; however, once again no long burn time is listed at all.
