I am not sure what point you are referring to. But my take is having moved onto step 2 (n2 lift through the velocity string) at 2000 hrs on the 15th, the flow was within the comfort zone @ 350 bpwd. 33.5 hours later it has dropped to 166/bpd at the time of the update.
Given that the recovery flow is being limited to a sustainable flow rate, by controlling the choke size to maintain top hole pressure in the range 200 to 400psi. So at this point they are only taking out what is coming from the reservoir. So if 166 is coming out 166 of displacement is occuring somewhere.
It is still early days as the higher DP needs time to work on the rock. As vapour space rather than water starts to accumulate at the rock faces, movement of gas out of the rock will improve. 88e indicate 30 to 35% frack fluid is the required number
