Tables 4-3 and 4-4 are very similar, and can be combined to provide results for attempting the various DCs in Table 10-2. While such a table is a good idea (whether based on character or task level), I would suggest that the table be populated with scaled values for all magnitudes of proficiency and difficulty at each level (0-20+). If the GM determines that there is a cap (or a combination is n/a), they can do that much easier than generating a scaled value.
The table values can be based on anything, and I would suggest they be evaluated based on the resulting days it takes to create an applicable item for half price (or of generating sp relative to the level's gp expectation) - on making that a relatively smooth function. The following table is an example of that, modified to provide more evenly distributed results (with decimals used for cp) for crafting an item 2 levels lower than the 'level', which are tied to the expected adventuring gains by level (Table 11-1).
Such a table creates the possibility of using it in concert with 10-2 to measure progress on any multi-check task (which would be useful for many exploration tasks as well).

This table does result from altering the base permanant item price for a 17th level item to 160,000 (and thus suggesting an 8,000 cost for 17th level formula and expected level gain currency), instead of 150,000 and 7,500.
