On our way to Hokers, we want to have about 6 Silk before starting Hokers so we can Silkspear the spines that fly upwards when hitting a Hoker (6 Silk gives us a minimum of 2 Silkspears on the 1st Hoker). As we transition out of Deep Docks Bellshrine, normally we dash out of room transition into pogo dashes, but sometimes this doesn't line up to hit the Brushflits that spawn towards the right side of the first pathway, because the Brushflits position is RNG. In Tener's 51m12s, I saw him do this line and it's quite consistent at collecting a large amount of Silk from the Brushflits without losing much time. The line is dash out of room transition -> pogo dash -> dash attack -> dash -> sprint jump -> pogo dash 3 times -> dash attack. (I haven't seen any other Bells runner do this line so my b if this is known)
If I compare to a line that doesn't collect any Silk, it seems like you give up about ~0.5s to have a lot more Silk consistently. Video 1 is tener's line, video 2 is normal movement(?)
