hetherb, according to Addax's PR you are absolutely correct. The have the rig for 5 holes in 300 days with the option to extend for another 5 holes and another 300 days.
The author of that article might be looking at the Work Program requirements, which I think is 5 holes in the first two phases (2 and for years). Since it's been a year since the execution of the PSC's, there's 5 years left.
I'll go with Addax's 300 days. They know what they are planning on doing.
