The entire feature is meant to be a type of courtesy to players in that a portion of the effort they spent on one PC can be transferred to a new one if they wish. But it’s not meant to be an incentive to accumulate XP with an existing PC for the benefit of a new one.
Using the level 10 example, a PC could have 54000 XP and still be at level 10. Half that is 27000 - just 1000 away from level 8. So the way the transfer is done now (by levels) is to hopefully avoid the rare occurrences where those who may be getting tired of a PC accumulate more XP with the intent to delete or kill it in favor of a new PC that can be immediately raised to close to the same level. Accumulating two levels for a new PC to gain one level is going to be much less practical, and much more time consuming, than accumulating 2 XP with the existing PC to give 1 XP to a new PC.
I will consider changing the transfer to XP rather than levels. However, the amount of XP would probably not be more than 20% or 25% of total XP (with an upper limit of 36000 to reach level 9), but not 50% of total XP since could be a bit too tempting...
