Can someone help me clarify how Time Patterns for DWFs interact.-- especially the Weekend one

ver= 13 Update3

In the Past the patterns in DWF were, I believe, used as follows
Avg x Patt1 x Patt2 x Patt3 x Patt4
& IFF (if and only if) a Pattern had a type =WEEKEND it was applied during (and only during) weekends -- [and others were always applied]

eg if Patt1=monthly, Patt=Daily, Patt3=Hrly, & Patt4=Weekend
then Patt3 was effectively the variation during the day (by hr) for ALL days
BUT on the Weekends it was modified by Patt4.
[ From HELP>Dry Weather Inflow
A pattern multiplier can be specified for each of the following:
  • Month of the year
  • Day of the week
  • Hour of the day
  • Weekend (a weekend pattern is only applied to Saturday and Sunday, otherwise the multiplier value is 1.0 for weekdays)

If multiplier patterns are specified then the flow into the node at any given timestep is (Average DWF * Monthly Multiplier * Daily Multiplier * Hourly Multiplier * Weekend Multiplier)
]

BTW. I also presume that the Pattern TYPE controls the way they are used NOT the postion they are specified (ie, it is the TYPE=Weekend, rather than a pattern positioned at Pattern4, that controls whether it is used during the Weekends).
???Can anyone cofirm this????


????NOW it seems as if:
The Hrly patterns are ONLY used on weekdays and
The Weekend Patterns are ONLY used on weekends

ie an either/Or situation, Thus, for the eg above;
Avg x Patt1 x Patt2 x ( Patt3 | Patt4 )


Can anyone confirm or deny this for me ... or correct me if I have the basic methodolgy wrong.
