Rewrite the phrase "various projective practices upon trending" to something more understandable
This sentence is not understandable:
"Various projective practices upon trending have been used to forecast progress, like burn- downs, burn-ups, or cumulative flows."
Upon consulting the dictionary, "projective" is a psychology term meaning “relating to the unconscious transfer of one's own desires or emotions to another person.”
And, "projective practices" seems to be an architecture term (as in buildings) having something to do with the theory of planning.
Further, “...upon trending” is an odd construction that places a context in which other actions appear to be happening but I don’t understand what this means in this context. For example. “Upon [performing] trending, the statistician discovered an anomaly in the data.” But that use would make trending a verb form, and the word form "trending" is an adjective apparently.
I've asked several Scrum experts, and they seem to agree that it does not make sense as an English sentence, but do refer to a blog post that explains that it really means “people have tried using various tools like [list of tools] to capture trends in order to predict future progress”.
I'd offer that it shouldn't take a blog post to explain something this simple.
I hate to make a critique without proposing an alternative but because I really have no idea what it's trying to say, I'd be guessing to propose an alternative.
