I didn't check the map at the end because I did this run years ago, so here are the timestamps of checking each area:

• Brinstar: 58:08 (I unfortunately didn't check the map after this point. I get the last tiles heading to Tourian right after this, then I get the final map tiles above the starting area at 1:31:05)
• Norfair: 1:41:57 (I didn't actually check the map again after getting the last tiles near the Crateria elevator, but this is the last full check I make. 1:42:39 is getting the last tiles)
• Kraid: 1:36:43
• Ridley: 48:51 (I get the last tile right after checking the map)
• Crateria: 1:43:32 (Similar situation as Norfair, but I got the tiles immediately after)
• Tourian: 1:30:25
• Chozodia: 1:55:49
