Possible Nursery Bug?

[Ghost]

Playing around with belt speed upgrades, I found out that the nursery production speed of Sage and Flax with advanced fertilizer always matches the current belt speed (Upgrading belts to 240 items per minute makes the nursery with advanced fertilizer produce 240 flax/sage per minute; at 120 belt speed, nurseries make 120 flax/sage per minute).

This does not happen to redcurrant plants though, which stay at an even 60 items per minute regardless of belt upgrades.

Is this a bug? Am I building incorrect item ratios around hyper plant production due to belt speed increases that will break in a future bug fix?

it is because of how much V each fertilizer grants. advanced fertilizer has 144 V/s max and red plants need 144 V to produce, 1 item/s or 60/min, while flax and sage have 24 and 36 respectively. the max rate should be 360 and 240 but since the belt speed is only 120 in this case, the system limits it to said belt speed.

Thanks, this explains the weird behavior. Presumably with enough belt speed, i could cut down the number of nurseries for flax and sage considerably, but mostly it is nice to know i am not building to a bug.
