On the 1 I had before , it had the formula part, say start £50, odds 1.01 ,
365 days. And it calcultaed it all for me.
BUT I could adjust the stakes/odds/days and it still calculated it for me - the ones ive been sent recently ,dont do this . I like to fiddle around, and see if im ahead of schedule etc
Cheers for owt you can do man
