First off, it's FHG, not HPG! I understand the confusion, but come on it's been more than a year!Originally Posted by Hey Robbie
I found this a really interesting subject so I'm happy to revisit it, forum etiquette be damned!
I think what you're talking about in terms of probability (Player A is a full 90 point boom or bust... he'll either make it big or flame out vs Player B has an upside of 85 but is pretty much a lock for 70) is just another way of looking at the risk profile or volatility of the future uncertain event. The way to capture that is to play with the discount rate within the ranges they sit based on the perceived risk of achieving it... if you see more production certainty you could assign a lower discount rate.One comment I have is that the modeling described above was revised to take into account total value as accumulated over the years leading up to a potential breakout, but does not account for any value that might accrue blow the maximum potential target. An idea I fiddled with last year was the idea of a potential distribution rather than a single percentage of reaching maximum potential. Imagine in any given year that we can estimate a probability that a given player scores in some range of points; eg a 5% chance of scoring from 41-50, 10% between 51-60, 21% between 61-70, 32% from 71-80, 25% from 81-90, 5% 91-100. This describes a potential distribution which could be used to assess value. While it is fair to use a discount rate of approximately 75% to a prospect of hitting the maximum (realistic) potential of ppg+, this player will still have great value if he misses that mark but does turn into a low 70s player, which is more likely, and some value if he maxes out in the 60s.
Of course the idea of utilizing this information is probably mere theoretical noodling (the province of science guys like your humble author) than a practically applicable method that might be fashioned by an engineer (eg our esteemed OP). But given that we've resigned ourselves to the fact that this is more of an art than a science, perhaps some element could be taken into consideration when assigning discount rates.
Of course if we believe the general shape of the curve is similar for all prospects, the idea may be simple to apply as a general correction factor, and this is probably part of what FHG meant in, "So, we do what engineers do: look for allegories!" But I think we have all pondered that due to some players combination of skill set, situation, style of play, etc., they will likely be a super-elite scorer in the 90+ range or a 60s type player, while others, who maybe don't have the hands or speed to ever hit 90, but have vision, work ethic, and surrounding talent, are a very solid bet to score in the 70s and low 80s for years. Which is the more valuable prospect?
Another approach could/would be to use "expected" production values, which could be assigned based on a Monte Carlo simulation of probabilistic result distributions of various forms, or more likely just taking an average between the player's low-end and high-end production scenarios -- ie analyzing based on a 3-year-peak figure rather than an upside.
I love me some Monte Carlo, but I think that would be a complete "garbage in, garbage out" approach -- you'd be looking at something more-or-less equivalent to a completely stopped watch: absolutely and perfectly precise for just two fleeting moments in a day.
