My math skills suck, but I'll try.... 14 Regionals reduced to 10 is ~30% reduction. DMs numbers are cloudy, so depends on where you get your numbers. Originally Kip said 110. 110 reduced to 72 is a 35% reduction. 90 DMs to 72 is a 20% reduction. If you take the original DM number of 110 DMs, reduced to 72 plus the 7 Energy DMs, that's 110 down to 79, which is still about a 30-35% reduction.
Kip threw out 600 as being the number for reps in the company. I think he is including the reps that aren't in the "pool"- Energy, TAs, etc. Either way, if you reduce 600 by a conservative 25%, that means 150 reps displaced. If you remove all the unaffected reps, that leaves about 420 reps and a 25% reduction would be 105 reps displaced. Either way, I think we are looking at ~100 reps being displaced, at a minimum.
