TDM, if you think you could remember a vortex table which is a 96x96 matrix, with departure separations in 10s increments for each individual type pairing, no more categories, can we use you in the sim?
For example, B772 followed by A321 might be 80s, but followed by an A320 it might be 90. Stick a B773 in the lead, and it becomes maybe 90s and 100s respectively.
