If there is NO time, then an adjustment is not possible and you need the 3 timers.
If the pad misses at the finish (i.e., single lane malfunction), you can make an appropriate correction using either a single button, or a single watch, if that's all you have. Having more than one human helps to make it more reliable, but a single button backup is sufficient.
(Otherwise, every meet would always need 3 human timers per lane, even if you had touchpads, just in case, and for sure that doesn't happen.)
