I did something similar a couple years ago, a series of 2 on/5 off short cycles. Got some decent gains, spread out over a longer period than if I did one longer cycle. Lost about half of what I gained during each off period until I didn't gain hardly anything the last cycle (didn't increase cals on that one, so there you go).
Tip from my experience: I was doing two weeks on (test p, mast p, tren a), followed by a two week PCT (nolva 40/20), followed by another 3 weeks before I started back up. The last week off was always a grinder in the gym, I wasn't blood testing but in hindsight levels were probably crashing about that time. Also, about a month or so after finishing the last 2 week PCT, I felt like I crashed - losing strength in the gym, losing motivation overall, no energy, etc. I did a 4 week PCT at that point, and felt fine after that
You probably don't need the 4 week PCT every time since you are jumping right back on shortly after that, but I would recommend a full 4 week PCT (if not 5 or 6) after your last one, just to level things out. Be interesting to see how things run for you in this set up. Try and keep track of day to day stuff as well, attitude, motivation levels, energy, etc., just out of curiosity.
Now to sit back and wait for the inevitable flaming. "Short cycles are useless!!!"
