Consider the following design, with these delays

Inverter = FO-4 Flip-flop t_cp-Q = 2 FO4 

Flip-flop t_su / t_h = FO4 Clock skew = FO4

Clock has 25% duty cycle

What is the clock cycle in a latch based design, assuming cycle stealing? 

Give the answer in units of FO4. For example, if its 10 FO4 just answer 10. For the purposes of this question, only solve the problem for setup violations, since I have only gave you the max logic delays and not the mins to permit a hold calculation.   Give the answer to one decimal point of precision.

Note this question is quite difficult because of the feedback and answer given by straightforward application of the formula in the notes is incorrect.
