If someone can get done in 5 days, in most cases they are over powered. Which on a crappy wet year can make them a local Rockstar, but if it`s a faux spring and they plant, get done too early that can lead to having to replant or living with a less than desirable field.
Planting is a very localized activity, it can be a wet spring "here" where 20 miles to the south they wouldn`t mind a "shot of rain" so I don`t know if "planting crews" would be as successful as harvesting crews, who can also be hostage to the weather. Some older farmers give up spraying, tillage and harvesting, but cling to doing their own planting 
It`s all "relative" but to have a +$200,000 piece of machinery that is only used one week a year and has to sit in the shed as the rain pours down, just as the old 494A 4 row did 50 yrs earlier seems to have a challenge to economically justify. Lots of things can be justified with $7 corn, $3 corn not so much.
