Hi Gian!
The mean value of ?30 is not 15 but 14.5.
(+/%#)i.30
14.5
Is there a point in using <.&<. rather than <. ?
Note that (((+/ % #)*1+#)-(+/))) is equal to (+/ % #)
When you apply a multiplicative noise, you should multiply by ^noise rather
than 1+noise.
So your bestfit calculation may look somewhat like this:
(],0{&<.0.5+(([:^0.01*_14.5+[:? 30"_)* +/ % #))90 90 90
90 90 90 92
