Why are there different end times for different lots?

For our online-only auctions, it would be too crazy if everything ended at once!  In order to give you more time to keep track of your bids, an additional five minutes is added to the close time for every 30 lots being offered (i.e. lots 1-30 begin to close at 6:00pm, lots 31-61 begin to close at 6:05pm, etc.).  For our live Gallery or Quarterly auctions, the auction will run approximately 100-125 lots per hour.  We are unable to post a specific close time for these live auctions, so please bid quickly if an auction is in progress.
