I personally would recommend trying to keep to the program as much as possible, but no punishment is put in place (unless you put one). The more days consecutive you sleep 7-8 hours the higher the chances for an LD (In my opinion). If you have a vacation, tragedy, parties, major events, or anything like that, you don't want to be some crazy person that is like "I know we are all having a great time on our vacation, but I need to go LD" This is the reason that I put 15 days as the exception, because then if you like partying on Friday or something similar you can do that, and one week you can do it twice. I don't go out drinking or really have many unmarried friends, so I don't stay out late ever. If you need more days give it to yourself. Life > LDs, but remember that LDs can enhance life if you want them to.

Yeah, you can link a punishment if you wish or have all of them if you fail. All up to you. If you don't say anything, then I will assume they are linked, which will change how things appear later on. There are a few things that I will have on this that you guys don't know about yet that will be optional, but should enhance the Summer challenge.
Ok, got it! Thanks for the reply. I will try to stick to the schedule whenever possible, I also find that a regular schedule helps to LD more often. Sometimes there are unavoidable disturbances so will use the 15-day allowance when necessary.

Well, in my case I prefer that each individual challenge is linked to a the punishment as per sequence. Things that we guys don't know about? Hope there won't be something too harsh like perform 50 RCs a day or take a cold shower for 10 mins. Hahaha! Oh, well, now that I have enrolled, will have to finish this up. If not heavily lucid, I will probably end up with an improved body and mind, I hope.
