I could see arguing that either way. Longer fields are capable of more
precision and so may need more buckets to predict. On the other hand longer
fields take more space and take longer to compare so to make consistent use of
resources you would want to avoid storing and comparing large numbers of them
whereas you could afford much larger targets for small quick columns.
