One more option has been added to the COSB functionality – the hourly rate competition with your last year result. It’s possible only for contests from WRTC archive – https://contestonlinescore.com/archive/wrtc.php. If we have your call in the last year contest archive you can get both scores current and last year. For example if you are running ARRL DX CW 2020 and we have your call in the ARRL DX CW 2019 archive you could get both year rates:
Just find out your call with the “dash” and last year. For example my last year hourly rates is associated with VA2WA-2019 call. COSB provides rates in a real time. So you can make correction to your contest strategy on fly!
