My activity didn't increase after the 2 week period towards the end of february.

My understanding is that activity increases by (# of posts - activity) with a maximum of of 14 activity every 2 weeks. I had 28 activity points before my last few posts in february so by that reasoning, I should have >28 activity, correct?

I'm sure that I'm missing something, what is it?

I'm super interested in IOTA because of how ambitious of a project it is. I'm fairly new to the scene and would love to get some unbiased opinions on where IOTA is in its development, the feasibility of what they're trying to do, what exactly are they trying to do, and what they're having issues with...
Also, what are the implications if they succeed?
Thank you for your input!
