overlapping of rules? - Palestine

[Christina Lawrence]

Hello!

Currently the rules for Palestine are:

Rule Palestine     2010      max       -              Mar        lastSat   0:01       1:00       S
Rule Palestine     2009      max       -              Sep         Fri>=1    2:00       0             -
Rule Palestine     2010      only       -              Aug        11           0:00       0             -

The first line is fine, this is the start-date and says it's in effect from 2010 going forward.  

The last two lines appear to overlap.  The second line says the end-date is the first Friday in Sept starting in 2009 going forward (including 2010).  The last line says in 2010 the end-date is Aug 11.  I do see that Alexander Krivenyshev (2010-07-20)pointed out the "Clocks to go back during Ramadan--and then forward again"

I believe this Aug 11 end-date is a one-time exception. So, does the following make sense, to avoid the overlapping rules for the end date?

Rule Palestine     2010      max       -              Mar        lastSat   0:01       1:00       S
Rule Palestine     2009      only       -              Sep         Fri>=1    2:00       0             -
Rule Palestine     2010      only       -              Aug        11           0:00       0             -
Rule Palestine     2011      max       -              Sep         Fri>=1    2:00       0             -

Would this not be more acceptable?  I have yet to encounter any overlapping of rules previous to this one.  Am I missing something?

Thank you for your time!
