I agree. You need to look at that net time saved, not the gross.
In addition, if you're at a terminal on a new server, or someone else's station, all those aliases will be gone.
For me, that means any special aliases or scripts had better be awesome enough to convince someone else to use them... Or infrequent enough that I can't be bothered to remember the whole command. Or just so useful that it's worth overriding the above.
Shortening a 3-letter command into a 1-letter command is not going to fit into the above. Especially when I will have typed 'git' before I remember that I can just type 'g' instead, since I touch-type without looking. It just flows out.
