Sounds normal for the kind of system you seem to have. Higher numbers of
degrees of freedom require closer temperature spacing.

Is there any other way to determine the spacing? Can the equation

Yes, but if you want exchanges to occur, there are constraints on the size
of k. What's so hard about T(i+1)=T(i)*k?
