Yes, I think we did it the way, Tommy, you might have thought we did, but I’ll say it for others. We have eye comfort on a lot of our units, tens of thousands of units, and we have access to the run times, so we were able to go in region by region, not quite zip code by zip code but region by region, adjust for the weather, make other adjustments we thought were appropriate, and then we were able to come up with the average run time of the units on a year-over-year basis, and that was around that, say, 30%, plus or minus 30%, but right around 30%. Then I did some Kentucky windage by just saying it’s probably not going to be that on an ongoing basis because we won’t have as many people working from home as we did last year, so then I just said, say it’s 20% instead of 30%, and that sort of felt right, at least from the world that I’m living in, because we still have a lot of people working at home and we will continue to have people working at home, even when we get to the other side of this. That’s where the 20% came from, and then 20% times 15 gets you three, 15 minus three gets you 12, and then I just sort of rolled into it to say the weather is 5% warmer the last three or four years than it was when we originally came up with the 15-year data point, and that 5% weather has a higher impact than just saying you reduced the life cycle by 5%. I didn’t even try and quantify it, but it’s sort of exponential in nature, so it’s sort of somewhere between 5% and 10%, maybe closer to 10% from having 5% warmer weather, and that’s sort of in the mix also. I wanted, as I’m repeating myself, just to introduce the concept of very traditional way of saying, okay, how many units were installed in 2006 and we’re 15 years forward, so that means it goes to zero - that’s not the way to look at this, and I think we all knew that there are other variables in play because it doesn’t explain what’s been happening in the market for the last couple years. The bears have been predicting resi turning for a while now and they’ve been wrong, and the reason they’re wrong, we think, are these new variables.
