This is good stuff. Thanks for sharing.
For those worried about the work, there are a few mods out there that do the math for you.
Muted 79's HOF MONITOR
Tysok's WS and HOF Measurements -not sure if this one will work with 12
Lighthouse Keepers OOTP Companion - this one will also show you the year retired and service time...and again, not sure updated for 12 yet.
Muted's should work for sure and Tysok's and Lighthousekeeper's tools are ones that we should lose, so I hope they convert if needed.
