Update Ticket History Job Frequency

Hello! This is probably a silly question, but currently we have a job that runs the update ticketing history procedure once a day. Would there be any harm with running it once an hour? I'm trying to implement a subscriber add-on discount pricing rule with exclusion list based on # of tickets purchased per production. We currently only allow our subscribers to purchase 10 additional discounted tickets per production (we have five mainstage productions per season). The exclusion list would definitely help, but I am getting tripped up in my implementation because the ticket history is only updated once a day... this doesn't really help with our real-time online purchases. I'm just worried that making it update hourly may bog down the system... but I am not sure. Thank you! Kristine
