Increasing intervals beyong 1 (default value) result in a huge slowdown, 
and can cause artefacts.
With method 3, you should use at least 3 samples and the default is 10. 
samples 100 not that slow, and way faster than intervals 10 samples 3,1.

confidance and variance are used to adjust the number of samples per 
intervals and are totaly and silently ignored when using method 3 as 
there is only 1 interval.

All in all, you only need to adjust samples.
