Some leagues will have bonuses at 100 yards rushing/receiving or 300 yards passing, or at similar levels. Full Impact can assist you in accounting for this, though perhaps not in manner you would guess. Please consider the information below carefully.
Full Impact reports are created using projection data, but your league's scoring systems will run based off after the fact data recorded throughout the football game. The difference between these two data set is higher than most people realize.
Consider a QB we projected to throw for 299 yards who ended up throwing for 301 yards. This two yard difference in a league's scoring system with a bonus at 300 yards is important, but really this would be a projection model success, off by only two yards! Similarly, a couple seasons ago, we projected Ben Roethlisberger to average just under 300 yards a game and Drew Brees to average just over 300 yards a game. Obviously we were not predicting that Roethlisberger would throw for less than 300 yards every game and Brees for over 300 every game. We were really just indicating that both players had roughly a 50% chance of hitting that 300 yard mark.
When using 4for4 projection data, we want to avoid the true or false nature of league scoring systems which use after the fact data, and instead create statistical correlations of likely outcomes of our projection data.
Full Impact can approximate the increased value of certain stats that bonuses offer.
Our projection models basically indicate that the more passing yards a player accumulates, the more likely they are to hit a cumulative bonus at a set point. Sensibly, a QB projected for 300 yards is more likely to hit 300 yards than a QB projected for 280 yards, who is more likely to hit 300 yards than a QB projected for 230 yards, and so on. The same goes for rushing and receiving.
So the best way to account for the increased value a bonus gives is to increase the value of that stat across the board.
Slightly weight your Full Impact settings towards a stat to approximate the value of a bonus.
If your league uses a standard "points per yard" measurement with a set bonus point, we suggest decreasing the points per yard in Full Impact. Something like 18 or 19 passing yards per point (as opposed to 20) can approximate a small passing yardage bonus of 1 to 3 points at 300 yards.
For rushing and receiving, setting rushing yards to 8.5 or 9 yards per point (as opposed to 10) can approximate a small yardage bonus.
Don’t build the full value of the bonus into the yardage, because most bonuses are relatively rare occurrences.
And if your league uses ranges for scoring, consider a more linear distribution of points within the Full Impact ranges.
Bonuses hit less often than you realize, so consider ignoring smaller bonuses all together.
We should not overestimate the impact a small or rarely hit bonus makes. Unless they are significant, it is generally best to simply leave bonuses out of your scoring rules at 100 yards or more for rushing/receiving and 300 yards or more for passing. It's relatively rare that players hit these bonuses, and factoring them in on draft day will rarely contribute a positive result. Your goal should be to draft the best players and let the bonuses sort themselves out.
