Is it appropriate that a title which lasted exactly 150 issues should be volume 150?

There were also seven Annuals; and five issues of Giant-Size Spider-Man, which was a "companion title" to MTU. Each issue of GSSM featured a guest-star who was given equal billing on the cover, and was released in a month when the Human Torch was the lead star of MTU. GSSM should be included in the MTU Masterworks.
