Pedestrian path gradient list management

Hi,

I’m after some advice in list management. I’ve created a Grasshopper definition that measures the gradient of an existing pedestrian path within a landscape and then assesses it against allowable gradients within Australian Standards AS 1428.1-2009 Design for access and mobility.

I’m able to get it to work perfectly for one pedestrian path. However, it gets messed up when I analyse two paths at the same time. Does anyone have any tips on how I can manage the lists from the two different pedestrian paths?

Here’s a screenshot of it working with one pedestrian path:

Here’s it glitching when I add two pedestrian paths:

Here’s a summary of the pedestrian path and ramp gradients in Australian Standards:

Here’s the Grasshopper definition:

Thanks in advance for any tips!
