Gate length in time division

[geremy]

Apologies for the dumb question but I'm not sure how to manipulate gate length in time divisions with a table. I have read the manual, and I understand the use of tables for ratcheting, but not how to manipulate the gate length as a percentage of single step time. I assume it has to do with the speed setting? I'm not talking about multiple trigs per step, but the simple length of the single gate played on each step. Thanks!
