"Realistic" is going to be different for each individual and each networking situation. If you are an outgoing individual who is attending a large function with 500 people, the potential is very high. If you are a shy individual, your goal is to meet the number that pushes you out of your comfort zone while being productive.
A networking opportunity can occur at an intimate dinner for 6, a movie screening, or a seminar (to name just a few).
I suggest you set a number goal that is:
1. More than you would normally reach out to
2. In line with the number of people who will be at the event
3. Do-able; set yourself up for success
Remember it's not about the number, it's about creating relationships with people and getting out of your comfort zone.
