Ahh, I've heard of doing that, but never actually known anyone to do that. I think I may be experiencing the same lag times that you did. I pitched a packet on Sunday early evening. Later that evening the airlock was floating, so I thought great. Then Monday evening still no krausen and it didn't look like there was any activity.
I rehydrated a second packet (I didn't hydrate the first packet) and pitched that last night, I'll see if anything is going on today.
