To make an up to 95 mL with water, or 700 mL of 95% alcohol up to 950 additive, the solutions will be slightly less than the indicated mL. Because alcohol and water mix in a way that is not exactly percentage if diluting to 950 mL. For example, a 70% alcohol solution may be prepared by diluting 70 mL of 95% alcohol alcohol, but for routine stock solutions it is easier to dilute to 95% or 950 mL.
