Hi there just another Wikipedia editor! I generally edit stubs or make new articles, so you might be here to check why is there a spike in information added. Please be civilised when discussing even though we may all have differing view points!
The amenities in Singapore locations that I have added are placed ONLY in accordance to what is commonly accepted, NOT according to URA defined boundaries, because:
Firstly if URA boundaries are used many estates would vanish and/or be pulled out of distortion.
Secondly if both URA and commonly accepted boundaries are used there would be many repeated contents in different articles.
Example: Siglap Centre does not lie within the URA Siglap subzone but is written under Siglap article because it is commonly accepted to be part of Siglap.
