That's his design philosophy. Of all the stuff I've read over on Speedtalk that Mike Jones has posted it appears to me he prefers to use a little less intake duration and spread the LSA to broaden the torque curve. If you listen to Chad Speier's engine on the dyno its very tame @ idle and yet it made more power everywhere. In a street or street/strip application on pump fuel that would be my approach. Less overlap equals less intake charge dilution by exhaust residual unless of course you need the heat of the leftover exhaust residual to help vaporize the mixture because you can't get it done after it leaves the carb or on the compression stroke because of too little compression or too late a IVC point for the compression to build and cylinder pressure.
I'm not Chad Speier. Just pointing out that there are different approaches to this stuff that gets results.
