No premanent irrigation but hand-watering

Hi, our project has no permanent irrigation but has periodic hand-watering as needed for extreme weather conditions. When I go to complete the LEEDonline form I am not asked anything further concerning the hand-watering. The comment from the FAQs above "Also note that you'll need to make sure there's no regular hand-watering going on, as sometimes even if there's not a permanent irrigation system the grounds are still regularly watered." suggests that the project should track/calculate/measure in some way? Although LEEDonline only asks to confirm no permanent irrigation (in this project situation there is not) and to provide a letter of confirmation from the facility management. This statement in the FAQs is slightly confusing. I just want to be sure there is nothing more for my project to include. Thanks.
