I know what you're talking about. The answer is no. If you happen to see the typewriter make note of it and that will be your save point, otherwise you have to keep going until you beat the stage or get another typewriter.
What screwed me up, was after death they throw the typewriter icon apparently always, never noticed that before, I had assumed i was seeing that typewriter because I had just cleared (what I assumed) was a milestone.. (lowering all the bridges in underground labratory in Leon quest). Now I'm thrown all the way back to that "puzzle" entering the combinations of 0-1-2
Because it easily took me 40 minutes to get from the part of entering the underground lab to the point which I died (the area right after you solve the "puzzle" of pulling the levers to drop down the metal bridges. At the very least, I would have assumed I triggered a save point right after that cutscene where you enter the room with the zombies in the glass tubes.
This area, if you are playing for the first time and fully exploring (i.e., opening every door, searching for BSA medals) and killing evrything you come across, easily takes 40 minutes.
There is no way you get a "save point" every 10-20 minutes, at least, not up to the point I have played so far, unless you avoid all zombies and race to the path the PDA directs you. Since you need a lot of money to buy those skill points, and the BSA emblems seem to be usually well hidden, seems best to slaughter evrything you find and search the areas for items and medals.
