Testing through a slotted liner can take some days to stabilise and "clean up".

The filter cake from the drilling mud requires some drawdown to get it to pop off and flow through the screens. So typically you unload the well, then start flow and some of the filter cake comes off rate goes up but so does bottom hole pressure then it drops away again as the ssmall section depletes allowing a bit more to pop off etc etc,

You would also not pull the well fully open too fast as you dont want to put too much differential on the liner as the mud behind the liner comes through it.

So slowly slowly is OK.

I'm betting we get 30 mmscf/d constrained by the amount of water they can put up to cool the rig from the flare.
