design spreadsheet

Thanks Curt for continuing to update the spreadsheet!

I've emailed it to the MH 38 group but am also putting it here for anyone that wants to use it. Note the name is no longer MHDD...

Since blogger won't let me attach it directly, I've zipped it as MHDD.zip and put it on Google Drive and shared it publicly - https://docs.google.com/open?id=0B1DON3zCNlIpTmhWbTR4TlJZTjA

Please let me know if you have any issues...
