Standard? Start Charge?

Some loading manuals just list a maximum charge weight, and simply suggest reducing that by 10% as a starting charge weight.
Some loading manuals list a maximum charge weight, and a starting charge weight, which is almost always about 10% less than the max charge weight.
I just noticed that most of the starting charge weights in the Lyman manual are at least 25% less than the starting charge weights. (at least for the pistol loads I've looked at closely.)

I'm thinking that might explain why I had so many unacceptably weak loads when I started loading, since I was basing the loads on data in the Lyman manual. Now, since I've started using data in some other manuals, I seem to start at a more acceptable load level.

Why are the starting loads in the Lyman manual so conservative?
