I have been getting slightly under 2 seconds at night and about 1.5 in the day. I belive the DSC-P41 is approx. a 1 sec camera and the board is approx. 1/2 second.
The only camera that I found that is faster is the 3.0 Cuddeback. This camera is around 1 second. The disadvantage to the Cuddeback is you cannot remove the camera and have to view the pictures on another device or on your computer.
With the Trailghost I can use the camera for vacation or parties. This keeps the wife happy

. For the extra .5 to 1 sec it's worth it. You can also view the pics in the field and delete the ones you don't want.
The guy that makes the control boards for the Penn's Woods also makes the Trail Ghost boards.
