Final answer:
To evaluate the frequency of virtual meetings, assess the purpose and needs of the meetings, not merely technical capabilities or attendee locations. Surveys to understand travel patterns for effective scheduling can be done throughout the year and on varying days for the comprehensive data.
Step-by-step explanation:
To determine the frequency of virtual meetings, one would need to consider various factors rather than taking a technical or geographical approach. The key is understanding the purpose and requirements of the meetings rather than just the technical abilities of the platform or the locations of attendees. However, to help with the survey mentioned in your additional information and in the context of evaluating meeting frequencies, you might consider conducting surveys during different seasons, using flights from various locations, and on different days of the week to collect comprehensive data on travel patterns that could influence scheduling of virtual meetings.
