Although frequency-of-clip (FOC) is a very precise formula, it is not always an exact science on the turf. Superintendents new to FOC will work with their technicians to experiment with different settings, usually moving up or down 10 to 20 per cent at a time. To monitor changes, superintendents may use a prism to evaluate stragglers and record Stimpmeter readings after FOC changes. Some superintendents actually weigh clippings to compare grass volumes at different FOCs.

After experimenting, superintendents will arrive at an ideal series of FOC settings for:
● daily play;
● post-topdressing or aerifying;
● tournaments; or
● severe weather conditions.

Some mowers allow up to six FOC presets that can be programmed into the mower’s control box.
