### Formula to effectively mimic stolen bas

Here is a formula suggestion that I think would more accurately assess the SP rating (whether or not players will steal a base given the chance).

Taking triples out of the equation (can stay in, but here is a simple formula).

Plate appearances * (OBP) = times on base.

Times on base / (divided by) steals = times on base for every 1 steal.

Anything below a 5.00 gets a 9. Anything below a 6.25 gets an 8.

5.00 would indicate 1 steal for every 5.25 times on base.

Plate appearances are easy enough to import, and could factor in for other offensive categories.

At bats count against players who do not take a walk and hence drives down their SB/AB. Thus the above formula would remove that heavy bias.

With this formula you can take Juan Samuel 1984:

737 plate appearances * .307 OBP = 226 times on base.

226 / 72 stolen bases = 1 stolen base per 3.14 times on base.

Compare this with Ricky Henderson 1980

722 plate appearances * .420 OBP = 303 times on base.

303 / 100 stolen bases = 1 stolen base per 3.03 times on base.

Almost exactly the same! When you factor in Samuel has 19 triples to 7 for Henderson AND Samuel had 34 triples or homers compared to 13 for Henderson. The triples or homers count towards times on base but are NOT stolen base opportunities.

Additionally, you can go one step further with the following formula:

Plate appearances * (OBP) = times on base.

Times on base - (minus) home runs - (minus) triples = Stolen base opportunities

Stolen base opportunities / (divided by) steals = stolen base opportunities for every 1 stolen base.

Here if you apply this formula to Juan Samuel and Rickey Henderson, you get 2.67 for Samuel and 2.90 for Henderson, rating Samuel as more likely to steal a base with an opportunity than Henderson.
