Is it possible to add both Double Check and Premium Request options?

It is possible to choose both Double Check and Premium Request for one job.

However, this is only when there are more than two translators in the list specified for Premium Request.

The reason being that you need to ask more than two translators to do Double Check.

When you choose both options, two freelancers within the list will work on the first translation and Double Check, respectively.

Also, if you choose both options, the fee required will be 3 times more than the regular fee.
(see chart*¹)

This is because in addition to the regular fee (1 character = 1.65yen *²), the following option fees are required:

Premium: ½ of the regular fee
Double Check: same as the regular fee

If you choose both options, it means that there will be a Double Check done to a Premium Request, and an option fee of the same amount as the Premium Request will be added on.

Therefore, in case of a 100 character translation (required fee: 165yen), the total amount can be calculated as follows:

Premium: 165yen x 1.5 = 247yen
Double Check: 165yen x 2 = 330yen
Premium and Double Check: 165yen x 1.5 x 2 = 495yen

Please see the chart below for details.
