I agree with MD apart from the comment re. the chronograph. The range will probably have one you can use, so why not take advantage of it?
Sure, don't get put off an accurate load if it isn't giving you the velocity you'd hoped for, but it is providing you with more information to analyze your results. I assume from the nature of your post that you are relatively new to handloading, so unless you are super-confident in your ability to shoot accurately and read groups, it provides another layer of information. Was that last group a shocker, or did you pull/flinch on one? The speeds may confirm.
Sure, 5 shot groups are better but you'll be pushed for time on a public night to get more than a few charge weights tested if you are shooting that many. And knowing the average velocity of your chosen load is good for determining maximum ethical range, drops etc.
