Does anyone know how an increase in the rate of reaction would present itself in the case of the Briggs-Rauscher reaction? Does an increased RoR cause the length of the oscillations to get shorter or just the time the reaction takes to run to completion?

I ask because I'm experimenting on it and seeing how changing the concentrations of the reactants changes the rate and potassium iodate (which I thought would affect it) doesn't change the length of the initial oscillations; does potassium iodate simply not have an effect or does the increase in rate not show itself by a change in the length of the oscillations?
