In the case of 2 separate governors one may act more quickly, and also both may be somewhat erratic and cause inexplicable detonations especially if we had two separate wide apart plugs as in the new head, when detonations would be very bad. Ask the critics to learn all the facts and then be very anxious not to hurt the feelings of those who have tried to produce something, by suggesting they are very foolish people.
