Projections with Methods H and L

I am working on setting up Methods H and L (Labor Quantity and Labor) in 9.1.   I put H at Level 7 with actual units.  I put L at Level 8 with Budgeted Production Units and Budgeted Production amounts.  I put I at all level 9 accounts where the actual amounts are being posted.  I don't have a projected amount, therefore, when I run profit recognition, the projected final cost is too low by the budgeted amount for the production units cost.   Is there any documentation or does anyone have any experience using Methods H&L that might be able to help me.
Thank you.
