Do you max your 401k/457b early in the year or spread contributions out?

So as of now, i contribute 13% to each. I have about 10.5 more pay periods to go before both are maxed out for the year (November time frame). ​ For those of you with higher than normal salaries, do you go high in the first few months or just spread it out during the year. With over 50% funded for the year, its got me thinking if i should go heavy early or just stay the course. ​ Just curious how you guys approach maxing out your tax deferred accounts. ​ For the record, Roth IRA is fully funded
