@s0600204: would welcome your input on this

Sure:

Personally I'd have thought that if the RRULE states a COUNT of 5, then 5 event instances should be spat out at the end.

However it appears I'm wrong - page 199 of the rfc5545 spec states:

[...] The final recurrence set is generated by gathering all of the start DATE-TIME values generated by any of the specified "RRULE" and "RDATE" properties, and then excluding any start DATE-TIME values specified by "EXDATE" properties. [...]

The PR conforms with the spec, is logically sound, and passes the tests. Go for it.
