Are you waiting well beyond the charge light coming on to fire the flashes?
Often, flashes are only 75% ready when the charge light comes on.

| Paul,

| Totally agree with your idea, but... I just tried again at 10 feet
distance,
| my two T32s only gave me F5.6 +0.5 EV. My room has white ceiling and very
| light color wall, seems the reflection is not so effective. Tried again at
| 1m distance, the reading is F16 +0.4 EV. In both cases still have around
| 1.5 stop under.... I started to think that my flash meter might have some
| problem. Does anyone have a flash meter want to join the test?
|
| P.S. I use a lumisphere for incident measurement, I think it should be the
| right way. On the other hand I found using fresh alkaline batteries with
| longer charging time, the power is 0.2-0.3 stops higher than using Ni-cd,
| may be due to higher battery voltage.
