Time trial, just make an effort to do it properly. Not much a hassle as Singapore has many infrastructures. The effort you try to justify and compare data, is more than just make a trip to the stadium or park run and do it proper.
Like i said, i agree with your statement if one is really anal about specific TT timings. This is why when i post timings, i put "TT" instead of TT, in quotes. (hope you get what i am saying)
I like performance but unfortunately i am not really that anal about the specifics and i dont really like track running round and round, though i do appreciate progression.
And i remember what you said before, if really wanna use GPS as a reference, that difference better be huge. Veryr ecently i tested was 420m on the GPS, 65 seconds, or say for 5k is 18:02, or 3k 10:15....
So of coz if really wanna compare, i'm not gonna say that im faster than someone who can run 70s for his 400 on track. Or 5k 18:30 (heck just round it up 19 mins lah.....

). Or 3k 10:30 - 10:45, but i rarely see folks doing 3k tho....
ps. I also know some GPS readings are
TERRIBLY off, eg 5.03 GPS is not 5k track, more like 4.5km track.
Or some races like Skechers 10k is 9.1km on GPS and god knows maybe actual distance possibly 8.95km or what.... these outliers are for another story.
