Confusion between decay time and decay rate in documentation Persistentmotion plugin
In the documentation for the PersistentMotion plugin decay-time
is described as in units of MCS, and is directly inserted in the formula for computing the new target direction. However, the 'decay rate' (MCSduration / decay-time) should be used in the formula instead (code here: https://gitlab.com/morpheus.lab/morpheus/-/blob/master/morpheus/plugins/motility/persistent_motion.cpp#L59)
(Try inserting dt = 50 into the formula, you can see how it doesn't make sense)
EDIT: While you're at it could you answer something else :P In the references I see https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3044241/ but this paper using a different decay mechanism, can you explain why you choose for a different formulation (both in the delta as in updating the preferred direction)
