So you will spend less days, spend same number of days in Germany as advertised, and leave on time? I don't think you will have any problems here.
My experience tells me that Schengen passport control has very little interest in the itinerary that you have used to get a visa, they're concerned with the itinerary that you are traveling on. Given that you have this outbound ticket all the time with you, that should suffice on both entries.
