Increase slowmover and reduce instability

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:

15+0.05
LLR: 2.96 (-2.94,2.94) [-1.50,4.50]

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