All I can say is that in my case, a robust backflow cured mine of having not-great flow after I took it out of storage. By "robust" backflush, I filled the syringe and then used as much force on the syringe as I could muster by holding the syringe against the side of the sink for a couple of backflushes. Used municipal water which is chlorinated.
But in use when camping, I just do quick backflushes of maybe a half cup of water after each batch of water is filtered. With the water bottle method, you can't get as much pressure on it with finger squeezing as you can with a syringe, thus my quick backflushes were pretty weak in comparison to my syringe backflushes. But my quick backflushes still reached crystal clear water after only a few ounces went through.
And as I noted above, I plan to do a robust backflush before and after every trip, so I am not going to worry about it.
