Yes, shortening it will decrease that time. What Jamie was explaining is the difference between a single tap like you said you you and a double tap. A double tap is pressing the rocker top or bottom twice in 'rapid' succession. Many time people will use a single tap with a ramp like you have setup and a double tap for a snap - basically instant on like a regular light switch. If you never want to use the double tap feature then you want to make that delay as small as possible which will make the light react faster. But, if you do use the double tap feature, if you have the setting at the lowest, you may not be able to click the paddle twice fast enough to be considered a double tap. In that case you would need to increase that delay which is essentially the amount of time the switch will wait after one press to see if you are going to press again before it sends out the command. Hope that helps...
