I think counters are the best method and spreadsheets are arbitrary, pointless and stupid. Oh Okay, being serious now. I think both methods have their pro's and cons. Using a spreadsheet would be pointless for me, because it would just be full of green squares. But there are some examples where it would be really useful for other people. Here are a few that come to mind. User A abstains for the most of a month, maybe even longer but relapses on let's say, the 30th. 31st, his counter reads 1 day, he makes an informative post but his credibility is immediately put to critique because he relapsed yesterday. It doesn't matter about his previous run, all that matters is his counter is on one day. Another: User B can't stop relapsing. In fact it's as if he's barely trying. With a counter, it is always around 1-2 days. This is an issue, because you and himself will never see his relapse history. He might even be compared to user A above; even though their abilities contrast. With a spreadsheet, his consistent relapses are clear as day to both himself and other users. Seeing a tonne of red boxes (or whatever colour you're using) might instigate more change than if his counter was simply hovering around the same no.
