Also, if anyone has an excel spreadsheet they use to do this sort of tracking,
A heads up for those who don't know:
You can copy and paste the player skill numbers from BuzzerBeater Scout into Excel or OpenOffice.
First make sure BBS is set to numerical rankings for skills.
Simply click on a player and use control-C to copy the data line. Then past it into excel. You'll need to allow for the blank column in front of and following the name. (I think one these pastes the uniform number, which I don't have). You'll have to delete the age and height columns, which don't change. I delete DMI, but you can leave it in, if you want. I delete the position calculations, too, but again you can leave them if you want to see the 'effect' of your training on your players projected performance.
To track changes, you'll need to have weekly .XMLs available. Make sure your players are on the same rows of each spread sheet (after transfers, you'll need to redo your sheets). Then enter the formula that subtracts last week's JS rating from this week's. Copy that across all remaining columns of the row. Copy the formulas in that row all they way down to your last player. you'll now have mostly zeros, but a few '1's in the cells where you had pops. There might be '-1's in stamina, but life has its disappointments, too.
This will also calculate experience pops, the only way I've found to do so automatically.
Hope this helps others track pops.
