Table

I've added a table for the I want to become stronger choice to simplify the layout. I'm not sure where to fit the No/Marvin responses though. Also, the fielder/pitcher heading is a bit confusing at it doesn't look that different from the other Treatment Options. Maybe the entire section should be indented.--Odawali 02:39, 2 May 2008 (CDT)

I successfully used a Yes card yesterday for my CF with the I want to become stronger option and received the following gains, +1 TRJ, +15 STR, +1 SPD, +1 ARM STR, +1 FLD. All my stats were kept at 14 to prevent the chance of certain stats not being raised and causing confusion over what the surgery can actually raise or not.--Tgjason 15:13, 8 May 2008 (CDT)

I also just failed on my challenge on the same fielder and these are the changes it made; -1TRJ, -20PWR, -1SPD, -1ARM STR, -1FLD, -1E RES, Acquired Durability 2, Vitality decreased--Tgjason 17:56, 8 May 2008 (CDT)

Confirmed, got near the same results (my fielder's stats were near 0 though, so i could not map all of the losses)--rsoohoo 05:55, 6 June 2008 (UTC)

Glitch

I underwent the operation wearing a +2mph Ace Stud, and afterwards its gain got reduced to +1mph, in both successful and failed outcomes. I suspect the +2mph items themselves are a byproduct of some kind of glitch (they're always in stock on the same week, and no matter how many times you reload, their gains are fixed at +2mph for that specific week), so I think it could happen to +2mph Heavyweight gloves and Accelerator Soles as well.--Odawali 05:16, 8 May 2008 (CDT)
