Perhaps you could allocate an evening as a tuning session, so everyone can have a go?
Walkback is generally done at say 40 yards down to 10, at 5 yard intervals, on the same boss. The distance can be varied depending on the bow. A particularly fast bow might need a higher spread than a light bow to get the pattern spread over most of the boss. You want the shortest distance arrow near the top of the boss, then walk back five yards each time and shoot another, so the furthest distance arrow is near the bottom of the boss.
In theory, you could do it at different bosses, but you would need several at five yard intervals to see enough definition in the pattern. It also means moving from one boss to another, and it is best to have as few variables as possible.
You can't use bareshaft to tell you the button position with any certainty, because it can't differentiate between errors due to centre shot and errors due to spring tension. The walk back method will give some sort of pattern of arrows. Centre shot errors give a different pattern to spring errors, so it tells you which to adjust.
Having said all that, any tuning method will only give perfect results if you are a perfect archer! You need to be sure that any variation is due to the tuning and not just a slightly duff release or whatever. It is often a good idea to repeat the walkback to check the pattern is consistent before adjusting anything, or you'll get yorself tied up in knots. If the pattern is not consistent then just get the tuning roughly right and work on your technique.
