Thank you for your kind note. As you have noticed, Mr. Selfridge isn't onscreen quite as much this season. This is completely due to Jeremy Piven's busy schedule rather than the thousands of letters we've gotten from viewers noting that anyone with his unrelenting enthusiasm would have died before they turned five.
However, Mr. Selfridge remains the moral center of the show, so whether it's more accurate or not we will probably not rename the show, as you suggest, "Some Guy Who's Freaking Out Because He Has Too Many Kids And A Girl Who Is Seriously Overworked."
All the best,
