Increase slowmover and reduce instability

uriblass · mcostalba · commit bb83a417cb70 · 2013-10-08T21:24:21.000+02:00
These two changes go in opposite directions and it
seems that the combination is stronger than original.

Here are the positive tests at various TC:

LLR: 2.96 (-2.94,2.94) [-1.50,4.50]

LLR: 2.96 (-2.94,2.94) [-3.00,3.00]
Total: 2570 W: 527 L: 422 D: 1621

Unfortunately there is also a bad result
with one sec time increment that needs
to be further investigated:

12+1
