It doesn't seem to be.  I know you hit L2 to lower the values.  So first up is the seconds value. I hit L2 until the lights stop changing.  I believe all 4 are yellow. 
	I click the mod button on the back, and this should take me to 100ths of seconds. yes?  I change this the same way until all 4 LEDs are yellow, click the mod button.  Then for the last group, this is the 10's of seconds.  I alter this the same way only the lights are different this time.   I click L2 until the top Left is green and the other 3 LEDs are red.  I assume this means the lowest number of tens of seconds possible.  By my understanding this means the button should be pressed 25 times a second?  This can't be right as I'm able to click x faster with my thumb.  Please help!
