I don't believe that to be true only because that would mean they would eventually be "full" after a certain amount of time. I feel its easiest to see the time effects when you look at shard amounts collected. The low end appears to be about 150ish and the high end appears to be somewhere in the 280s.

12hrs seems to be the max time required for a currency spawn and the low end seems to be 6 hours.

If you waited 12 hours or more to collect you'd expect to see the same amounts but this isn't the case.

On 4/3 I collected off my Thwok at 7:59 PM and didn't collect again until 8:20 AM the next day. Over 12 hours between collections... and the reward was 183 shards.

Similarly my Poewk on 4/6 went a hair under 12 hours between collecing times and i got 284 shards.

You could argue different coin accrual rates but I doubt this is the case. I'd expect Thwok to be more favorable in that respect.

I agree with Wolferinex    that once the icon appears no further currency accrues. In my experince the quicker that icon appears the less you get.
