willadvise, the bias in Singapore is
VERY real. I've personally been involved in about half a dozen or so instances where after being in front of a SQ aircraft, we've been vectored south (for RWY 02 coming from Aussie) and joined final at 20-30 miles when the following SQ has been given vectors in front of us and joined at 12!
There may be more aircraft and therefore you may get put behind SQ more often but when you've listened to the callsign one minute behind you for a couple of hours get the short vector, you know EXACTLY what it is!
