At your request.
I am a little short on time but found this one in a hurry.
I don't expect you to be familiar with this type of chart so in case you are wondering the dotted line is a holding pattern, not a racetrack.
How do you enter the approach if you come in outside the base turn entry limits?
As a matter of fact I am familiar with that airport, having just done a bit of TAWS assessment there.
I read Jepps a lot better than AIP source. Here is the Jepp for the IAP you reference and for the VOR IAP in the opposite direction. Note the second chart uses the same holding pattern, which makes a better fit for alignment prior to entry into the base leg. Nonetheless, the designers presumed the holding pattern "is suitable" for alignment to the base leg for either of these two IAPs.
