46:57 Yes. Hey, good morning, Bret. I'll be glad to talk to that and try to answer your question the best I can. Look, we're a couple months into this, Bret, as you know. As we said earlier, we did complete what we're going to do in February and that was completely rolled out to our entire organization. As you know, on the installer side, the professional side of the business it's far majority backroom hard parts, to your question. So that would be a yes overall, on your question there. 47:26 What I kind of want to just go back to that we talked about last quarter when we did this, Bret, is this is a absolute long-term play. It's a share gain play. It's something that we tested out extremely thoroughly. Really throughout the entire year last year, we tested our tests and we used a lot of science, a lot of data. We used isolated markets, we used markets, Metro markets, rural markets. And this was all about something that we felt like would absolutely be a share play and especially, a unit growth and gross margin dollar growth strategy over time. 48:06 As you well know, Bret, the way that our installers and professional customers, whether it be a independent garage or a national or regional account, they make their buying decisions based upon the overall value proposition. And us building our business, especially our professional business, which is how we founded our company on the professional customer, pricing is on down the list. It's critically important to have the right price, but all that falls behind getting a car off the rack every day for those shops, then buying from somebody they know and trust, the overall service and value proposition. And honestly, as an operator, I would just tell you that I feel even better about it as I did 60 days ago. The more we've moved on and seen the confidence in the team and what we're hearing from our existing customers and the future customers, potential customers that we're calling on, they feel really good about everything we're doing. 49:05 And lastly, I'd just remind you that what we did with pricing, we're still at a premium, like we said earlier. We don't want to be the cheapest. That's not a winning strategy for us. We don't feel that's a winning strategy in the professional business. And so we really didn't expect to see any reaction from our big public competitors nor the independents. So that doesn't surprise us that we're not seeing a lot. It was a very rifle approach, and I think Greg said that earlier. It was very targeted to the SKUs we felt like would not only give us a shot at moving more units with the discounted items, but the overall basket and the entire delivery with an entire job.
