I like it.
I didn't scour over all the percentages that closely, but by and large it looks reasonable and I think you will do well. As you get into your midforties and certainly into your fifties, I really really like twice per week programs for strength training. Those complete days off become quite necessary.
Here is my challenge to you:
Follow the program for a minimum of 16 weeks. Not deviations. Follow it EXACTLY as you have written out. Do not evaluate and make changes until you reach this date. Too many guys (myself included at times) stop and start programs like these and never really learn anything from them.
Good luck. Let us know how it turns out.
