First of all, you can't get to 105 LJ - the hatchet won't take you over 100.
More Importantly - Zared, you're wrong on mining - there's one BIG area it makes a difference.
The recycle amount for Blacksmithing is based on mining. The rate is 0.66% times the mining skill, rounded DOWN always.
As a result, since many items are evenly divisible by 3, you will get 1 more ingot back at 101.1 skill (66.726%), than at 101 (leather mining gloves, 66.66%) or 100 (straight GM skills 66.0%), because of the rounding.
This is critical when training, and recycling the made items to reuse the ingots. It's enough to make a huge ingot difference, in testing.
Note the following example, condensed from the smith FAQ, about using the Salvage Bag (which adds back an extra ingot per item). The same sort of thing applies for 100 vs. 101.1 mining. In fact, the numbers without the salvage bag are what you would get from only 100 mining WITH the salvage bag.
12000 ingots, used for 12-ingot items (for easier math purposes), 100% chance of craft success. Items are reycled, then ingots reused, until one runs out of ingots.
New data (see table below, to compare to the Smith FAQ salvage bag numbers):
100 mining, no Salvage bag: 2398 items made, 10 ingots left over (See progression below to compare to the charts in the FAQ)
100 mining, with Salvage bag: Identical to the "101.1 Mining, no salvage bag" numbers: 2996 total items made, 9 ingots left over.
From the FAQ:
101.1 Mining, no Salvage bag: 2996 total items made, 9 ingots left over.
101.1 mining with Salvage bag: 3996 total items made, 11 ingots left over.
So, without a salvage bag, you
make 498 less crafting attempts (and chances to gain skill) at 100 mining, compared to 101.1 mining (or 100 mining with a salvage bag). Have 101.1 mining AND a salvage bag, and you will get
1498 more chances to gain than at 100 mining with no salvage bag, starting with the same number of ingots.
The number of items made, translates to ingots used (as if you made items and sold them, instead of recycling), as follows:
100 mining (no bag): 28,776 effective ingots used, out of a real number of 12,000.
101.1 mining(no bag) or 100 mining(with bag): 35,952 effective ingots, out of 12,000
101.1 mining (with bag): 47,952 effective ingots, out of 12,000.
So, having 101.1 mining, will effectively save you 20% or more ingots over 100 mining, using training that recycles items. And, the lesser number of ingots used in the item's creation, the higher the savings will be (Ex. instead of 7(7/12), 8 (2/3) and 9 (3/4) ingots returned, respectively, in these examples for 12, a 6-ingot item returns 3 (1/2), 4 (2/3) or 5 (5/6) ingots, respectively).
