SGP's with non-standard categories

[cardinalkid20]

My league decided to drop batting average and replace it with slugging percentage and on base percentage, making it a 6x6 league in the process. I'm finishing up my rankings and about to convert them into my SGP-based formula, but I'm struggling with what I should use for my information because I have no data from previous leagues.

Its a 12-team, mixed-league. Can anyone help point me in the right direction?

Something you need to realize with SGP is there is a huge amount of wiggle room around the actual SGP. I shake my head when everyone struggles to get the SGP correct to one or two decimal places when it can be off by 10% and not change the value.



You need to figure out a point of comparison where you can equate "x" BAvg to "Y" OBP and "Z" SLP.

Maybe figure out the league average BAvg for the past few seasons. I'd add up the corresponding standings places for BAvg the past few seasons and get the average for the best, second best, etc. Here's an example:

0.2783
0.2715
0.2691
0.2667
0.2659
0.2641
0.2619
0.2604
0.2588
0.2571
0.2536
0.2466

The average of these is .2625

Now we need the equivalent OBP and SLP.

The MLB league average slash line was .253/.318/.396

So maybe set up a relation:

.2625/.253 = x/.318 where x is the equivalent OBP and

.2625/.253 = y/.396 where y is the equivalent SLP

x = .330
y= .411

The final step is finding where .2625 falls on the batting average standings, subbing in .330 and .411 then setting the standings places the same percentage above and below that mark so the DISTRIBUTION around that central point is the same.

0.278 0.350 0.436
0.272 0.341 0.425
0.269 0.338 0.421
0.267 0.335 0.418
0.266 0.334 0.416
0.264 0.332 0.414
0.263 0.330 0.411
0.262 0.329 0.410
0.260 0.327 0.408
0.259 0.325 0.405
0.257 0.323 0.403
0.254 0.319 0.397
0.247 0.310 0.386

Keeping in mind the actual standings don't include what's in red, that's just the comparison point.

You're most interested in the DIFFERENCE between adjacent standings places, not the precise OBP or SLP and I bet this gets you close enough.
