401k contributions with matching

[ImpalerMD]

Assume a salary of 650,000. Matching includes 100% of first 4% and then 50% of next two percent. What is the best way to maximize this match? I know there are limitations due to annual salary. Should I do 6% every pay period which will
have me reach the 20,500 max fairly quickly or is there a better way to go about this? Any advice would be greatly appreciated.

Does the matching have a true-up provision? time in market > dollar cost averaging usually

Just talk to HR. They were thinking about someone making 50k, not 650k when they designed the plan.
