Yes - it works in exactly the same way as the NSWTAB and UNITAB systems that you may be familiar with! A bit tricky - most people seem to lose 15%-100% of their turnover but a very small number of people do make a profit (less than 10% of users make any profit and only a few percent make a decent amount). So if you are going to use the system make sure you try it out on paper first as it's not as easy as it seems to make it work. :grin:
