The default duty cycle of 33% is less than the required by the I2C specs for the LOW period of the SCL clock. So, for 100Khz or less, use 50%H/50%L duty cycle, and for the clock above 100Khz, use 40%H/60%L duty cycle. That ensures the low period of SCL is always more than the minimum required by the specs at any given frequency.
