Can there be a difference in rewards given out for more quantities that have to be foraged?

I had an herb task to gather 6 yellow clover blossoms in X location, I get the following reward:

[You have earned 250 bounty points, 800 experience points, and 1250 silver.]


I then get another herb task to acquire 8 yellow clover blossoms in the same X location as before, I get the following reward:

[You have earned 250 bounty points, 800 experience points, and 1250 silver.]


Maybe have the base be 250 bounty points, 800 experience and 1250 silver for 5 (5 is the lowest amount requested for an herb quest). Then add 5% to BPs, exp and silver for every extra herb over 5 that is requested. You are out longer, taking more of a risk, you should see a slight improvement.

For the task to obtain 8 yellow clover blossoms with a bump in reward (seen above) would give an total reward of:

[You have earned 287 bounty points, 920 experience points, and 1437 silver.]


I know that harder to forage herbs give better rewards, but you don't get to pick what herb is asked to be foraged. It would just be nice if there was a base amount for 5 and if asked to obtain more than 5, you see a small bump for ever extra herb you have to forage.
