Here is the relevant page in the online user manual:
http://www.cymatic.co.uk/UserManual/TickOffset.aspxSo for example if you set the value to £1:
If you get lots of little matches say £0.10 each, then the offset bet will not be sent until the cumulative size of all the small bets adds up to a total of at least £1 (the size of the batch of bets). So you would need 10 small matches of £0.10, before an offset bet would be sent and so forth for the next batch of small matches.
Likewise if you increase this number to £10, then it will wait to send the offset bet until at least £10 of partial matches have occured. If you total bet is £20, and it gets 10 matches of £1, then you would send an offset bets of £10, then wait for the remaining £10 to be matched before sending a second offset bet for the remaining amount.
Kind regards,
Gavin
