4x10=40 for the early starts. They tried this at our shop and it faded fast. Think about the 830am-930am start times....You'd start at 0930, add 10 hours to that plus your 1/2 lunch (some had to take an hour) you'd be back at the shop at 2000. Not too much peddlin' happening around 2000 for certain sized centers, hell after 1800 the day was done so you'd get the "buzz" to come on in with a promise of "maybe" tomorrow.....along with that our first road cuts had a 2000 gate time.
So you were on a "10" but you'd never get a "10".
