If you increase the spark gap you might slightly delay the spark. To compensate you may have to advance the timing. Every little adjustment can affect others and cumulatively they can all have a greater effect than each one individually. That is the beauty of improving things. It becomes difficult to attribute exactly how much each change contributes but the total can be worthwhile.
