No accounting tricks, no tax advantage.
10% is before any of our expenses. It represents true 10% of any dollar that makes it to our account. This isn't an accounting afterthought, it's a structural reality of how our bank accounts are set up, no manual review until we give the money away. We don't claim any tax advantages, claiming the deduction is not mandatory and we think paying taxes is generally reasonable and we think that claiming deductions would be against the spirit of the deal.
