Math Errors

So I've talked to you in the past about some of the difficulties and challenges of building stairs. They're not easy. From a mathematical standpoint, it works out just like rise over run. You look at the hillside behind me and you say, "OK let's say we've got 15feet of height differential.  We've got a 6-inch stair, so that's going to equal 30stairs." Then we figure that at the depth 12 inches per stair, you're going to have about 30 feet. You measure, "do we have 30 feet?" And it all works out on paper. But when you get out in construction, sometimes things go wrong.  So, today I want to show you something that didn't go right that we're about to fix and what happened and how it could have been prevented. Right here we started building the stairs as we normally do. And the one thing I want to point out is these for 7 or 8 stairs look fantastic from an aesthetic standpoint.  They're solid and they're strong.  The problem is that they're too deep....
