I believe the 50% match the GP is referring to is 50% of what you contribute, not 50% of base salary. For example, if they put in 6% of their base salary, the employer matches with 3%. I assume from context that the 4% you mention is a straight 4%. That is, if you contribute 3% of your salary, your employer will match with 3% as well, but once you pass 4, the employer stops there. So if you're putting in 10%, the employer still just puts in 4%.
