glue question

hi,
so i’ve laminated two of three pieces of whacky wood around my form to make a table apron.
i’ve had it clamped up all afternoon now, using titebond III.

questions is: can i clamp on the final piece tonight, or will that be stressing the prior glue-up?
i know it only needs to be clamped for 30 minutes, but they say wait 24 hours before stressing, right? not sure if adding the other piece would be considered stress or not.

thanks.
