I guess I've been using a lie board for over 25 years. I still have my second one. The first wore out. There's at least one problem with the accuracy of the lie board. Mine is one of those black plastic ones, about 1/4" thick. The problem is the thickness. I try to use the lie board on a hitting mat or even on bare ground. Never on grass. If the board is on the mat or other relatively hard surface, the ball is sitting at least 1/4" above the player's feet. That's a small amount but it does change lie angle at impact. Is it significant? Well, after all these years on these pages, reading arguments over 10ths of a swing point, I imagine the significance is well, significant. One other, even more significant consideration is where in the golfer's swing contact is made. Ideally contact should be at the bottom of the swing - not fat or thin. That means of course, several attempts to get the bottom of the swing dialled in. That isn't always the easiest thing to do if the golfer's a hack (no offense).
The very basic way to use the lie board is the same as its been for years; stick a piece of masking tape on the sole of the club. Mark a center line perpendicular to the face. Hit a ball. Note the scuff mark. 1/4" off-center = about one degree of lie. The scuff is toward the toe - too flat, toward the heel, too upright. It worked for me for a lot of years.
