Narrative:
While in the published holding pattern at crepe intersection, ZLA cleared us for the ILS runway 11 at sbp. We were flying the pattern at 4000 ft, and as soon as clearance given, my student asked if he could descend to the 2400 ft GS intercept altitude. I looked at his government approach plate and saw the 2400 ft arrow was lined up with the holding pattern altitude. This is different from the profiles as shown on commercial chart maker products. See the enclosed copies comparing the commercial chart and government charts. The government chart shows no difference in altitudes on the profile, even though it exists! A 'profile' must depict a 'profile.'
