Yes but the issue is people that just come in forums and open a thread with a title like "xxxxx pips this week / month "
It is just fooling a lot of newbies that are impressed by the large number of pips.
I would suggest that when we see in the threads we follow such kind of sentences presented as results of a system (specially the commercial ones because in that case this kind of results may be published with the intentions of really fooling people) we just ask for results in net % and including the DD in %.
The reaction of the guy publishing the results to this request will be a good indicator on the validity of the system. If he gets angry or refuse to do it claiming that it makes no sense or finding excuses, then it just means that people can forget about that system.
