Publish global helper function: 'Single' and 'Multiple'

In the 'single' or 'multiple' global helper functions for Publish, is there concern if it gets called every second? My system is having trouble with 'loop_start' or 'loop_forever' so I just opted to use the 'single' or 'multiple' helper functions instead. The only functionality needed for my system is for the topic and payload to be published every second. Given that the 'single' and 'multiple' helper functions connect and disconnect on each call, would calling it every second be ok?
