Pulse is just a way of doing a servicing. The P/P*/M/M*/Mj all remain the same at the same frequencies - this policy is set by the IPT in conjunction with the aircraft DA. Pulse is intended to break these down into discreet packages that have a logical start and end, the advantage being that the processes during each stage are easier to manage and one aircraft found dead midway thorugh a servicing does not delay the whole line, just one small 'pulse' team.
This method is very traditional (the way we have always done it!), but people are starting to acknowledge that we over-maintain our aircraft and we can be more flexible. For instance, C17 has 6 (IIRC) Home Station Checks (HSCs, each taking between 5-14 wkg days) over a 2 year period that swallow up everything that needs to be done. There is no 'Major' equivalent, except that every now and then Boeing grab one of the fleet leaders and tear it down for an analytical critical inspection (ACI). The results of the ACI determine the content of the HSCs. This is a flexible policy that means we don't start tearing down brand new aircraft for in-depth inspection just to build in a maintenance stagger - this is one of the failures of the old system (has the first Typhoon had a minor yet?).
