Long Service Leave Accrual

I find that leave accrual, especially that for long service leave, does not have adequate decimal places to be calculated correctly by Reckon ie 10 years of services equates to 8.6667 wks and accrued at 0.86667 wks per year.  The government calculator at www.business.qld.gov.au/running-business/employing/employee-rights/long-service-leave/calculating has no less than 4 decimal places.  Why can't Reckon do the same and increase the number of decimal places available to use for leave calculations in general but especially for LSL.
