Actually, Scheffe is even more conservative than Bonferroni since it controls for all possiblle comparisons, not just pairwise.

Indeed!
In fact Bonferroni is very (the most) conservative approach to multiple comparisons.
In your case where k=4 the effective level of significance for each comparison would be .05/4 = .0125 .
