Is a 5-10 MM Fund Size Suitable for Co-Investing 10-15% in Series A Rounds with 50-100 MM Funds?

In my Investment Thesis the typical target is to invest in A round not as a lead but rather as a side investor with a value around 10-15% of the entire round. Am I interpreting the table correctly by giving the fund a size of 5-10 MM (which corresponds exactly to my experience and commitment as a team) that co-invests with Series A funds of 50-100 MM?
