At my race tracks back in the 70's... before the booth on the return road.. we just dropped a hand written time card (business card size with timing sponsor on it) down a PVC tube into a basket at the base of the tower.
Might have to go back to the future...at some time. BTW Gary years ago there were no reaction times and we didn't have fights. I've always though things would be better without reaction times.. You would have to really work to set up your delay box...
