When I say a lapse, I mean less than 4 posts or not visiting. As the today bar says, once you have visited and posted 4 times in a day, there is nothing more you can do for the day to increase your activity level. The issue is that a single day with 3 posts will prevent you from reaching 100% activity for 4 weeks, though its effect on your activity diminishes each week.

BTW, Lenny, assuming that you maintain >=4 posts per day from here on out, you'd win, since the first to 100% is the first to get 4 posts per day 28 days in a row.

Edit:

Lenny, you only posted thrice 22 days ago, so in 7 days of 4 posts per day, you will reach 100%, and until then your activity will remain constant.
