I agree - the system is completely fair and unbiased as-is.
The heartache comes from the duplicate "same post #s" like myself - when you end up as the fourth "#3" poster. Not sure if all the "Number 3's" have exactly the same time-stamp, down to the millisecond or what, but the system somehow sorts/organizes them as you see it now.
I have learned from this sale to no longer have a full reply typed out, and just keep it to a few random characters, and then 'Edit' my post after the fact. I think the few nano-seconds used to input the addtl. characters/letters cost me valuable time.
