Nice visual tool but wildly optimistic. Walk times to and from stations and during transfers can eat up huge amounts of time in a commute, and that assumes trains are running well. Discounting walking to station times which clearly can't be taken into account in this tool, the transfer times between trains are also not taken into account. Transferring over from any train that is taking you up the west side to one that takes you up the east side (or vice versa) of Manhattan takes up a lot of extra time but the maps treats them as if it doesn't matter what side of the island your original train will take you.
