Linear Weights… by batted ball speed
Jason sent me an email:
Hey Tango,
I was going to post this but couldn’t figure out how to put the chart into a post. I figured it would go best here: http://www.insidethebook.com/ee/index.php/site/article/the_hitf_x_database/
This is my first go at using LW’s, but I believe it’s correct. I am attaching the excel file if you want to take a look. I got the LW’s from here, but if there is a more up to date chart that I can use that: http://baseballanalysts.com/archives/2008/02/writing_about_t.php
If these results look good, I can also do it by hit launch and spray. Thanks
Results:
The harder you hit the ball, the better it is. Interesting that it doesn’t cross 0 until at least 90 mph.
