The pacing that will be used is a value between 3 and 4 including 3 and 4. But probably 3 and 4 will be the most used pacing.
Yes it can pick 3,4 and any values between 3 and 4. My remark was only valid if the response time before the pacing was always the same. Otherwise it will really pick any values between 3 and 4.
