Runspec numbers (as runspec prints) for both static and dynamic

Static
Base:
    Old: 447.dealII      11440        324       35.3 * 
    New: 447.dealII      11440        302       37.9 * 

Peak:
    Old: 447.dealII      11440        285       40.2 *
    New: 447.dealII      11440        268       42.6 *  

Dynamic
Base: 
    Old: 447.dealII      11440        327       34.9 * 
    New: 447.dealII      11440        327       35.0 * 

Peak:
    Old: 447.dealII      11440        287       39.9 S
    New: 447.dealII      11440        288       39.7 *

So, no effect in dynamic case. Is it right?
