variables	determined by
{X}	lastvalue1, add1, every1, whenmorethan1, setto1
{Y}	lastvalue2, add2, every2, whenmorethan2, setto2
{Z}	lastvalue3, add3, every3, whenmorethan3, setto3

column	meaning
lastvalueN	The last value we used for this variable.
addN	The increment between each number. When to increment is determined by everyN.
everyN	The number of issues between each increment.
whenmorethanN	The upper bound, after this this variable is set to settoN

Every subscription must have a matching subscriptionhistory entry, many of the queries depend on this.

If you want serials to be visible in various places then you must have status set.
