Backtrack every Page Monthly Structure
If you use this setting Q++Studio will also assume that the grid has an underlying structure of 42 days month blocks.
•For example, a 6 months on 2 pages grid, such as the one on the right, has tokens beginning with DayValue of 1 on the left page, and DayValue of 127 (3 times 42, plus 1) on the right page. Therefore Q++Studio assumes that the right page contains dates that are 3 months later than the left page.
That in itself is not different than the DayValues we would use for a Backtrack Every Month grid.
The difference comes from the fact that within a page of the grid, Q++Studio makes no attempt at interpreting the DayValues (ie. it treats the flow of dates within each page, as continuous).
•In the case of a Backtrack Every Page grid, the date of a token of DayValue of 42 will be one day less than that for a token of DayValue of 43, as long as the 2 tokens are on the same page.
•This is in contrast with a Backtrack Every Month setting for which token with DayValue of 42 can actually represent a later date than a token with DayValue of 43, sometimes by as much as 13 days.
Finally, note the effect of setting the option Outside Days to hide in "Grid Options"; the only days that are hidden are the days prior to the first month of the page, and days after the last month of the page.
