Solo player point rewards in GURPS?

Under normal circumstances in GURPS I believe players are supposed to receive between three to five points per session. However I may be gamemastering a solo GURPS game for someone who wishes to learn GURPS and I feel that considering the effort their character is going to have to make the point count feels a bit low.

Now what I wish to ask is what methods are there for rewarding a solo player in GURPS? Official rules or rules that are agreed upon by the fan base that dictates how many points should be given would be preferred.
