This effect is particularly notable when quaffing potions of experience - they give considerably more skill levels early on.
-One very important fact to keep in mind is this: ignoring cross-training, the total XP required to get a chosen set of skills to a chosen level is invariant.  That is, if you decide that your MiBe will go for L27 Axes, L27 Armour, and L15 Fighting, it does not matter if you train all three skills to L15 first and then train the remaining two to L27, or if you train them one at a time - at least for the purposes of total

-Absolutely none.  Skill training routes do not affect the total XP required to gain skills.  The fact that it is easier to gain skill levels when total XP is lower might suggest that training few skills early on is good strategy, but this is already considered optimal anyway.  The old learndb entry for skill points was "Only galehar <nowiki>[a developer]</nowiki> should know or care what these are."  It may not have been the most illuminating, but it is correct in its message: skill points are something the player has no control over, and cannot use to their advantage.
