OP- I would echo the sentiments in here with the caveat that if you can't perform the squats with proper form due to soreness, you can adapt (i.e. wait until soreness is gone) and "start" the program fresh.
Also something for all to consider:
I'm not one to buy into every study, but since I eat some amount of ginger almost everyday I would consider it as a means to prevent soreness and also to contribute to a healthy immune system. Even if the soreness aspect isn't really true/tat beneficial, you'll likely gain health-wise by including it daily
