This is a key part that you missed! Delete the work folder and whatnot and edit your shortcut to remove the -bigadv tag for a couple of days. You will see a huge increase in PPD just by doing that. Then, once you've finished 10 normal WU (about a week of folding, depending on which ones you get), you can edit the shortcut again to include the -bigadv tag.
|However, if this is your first time Folding, only Fold normal SMP WUs for the first 10 WUs. Then, you will qualify for bonuses, and then add the -bigadv flag.|
