For 65 character lines we set our software to:
Exclude letterhead for correspondence (what would traditionally be ordered from a printer).
Include all printable office note and report characters, and all printable correspondence characters other than the letterhead portion, plus the cc list marker, and copy stamp if applicable.
Include the keystroke press to space between words.
Include the keystroke press to begin and end bold, underline, superscript and subscript.
Include the keystroke press to tab.
Include the keystroke press to carriage return.
Exclude double counting bold, underline, superscript and subscript characters.
Exclude double counting the carriage return.
Exclude percentage add-ons for difficult dictators, printing, faxing and/or e-mailing.
With a 65 character line it should not matter how many characters are on a physical line (the software should take the total characters and divide by 65).
Some transcription services may use a 65 character gross line, which in our opinion is deceptive, as it actually means that any physical line is a full line, with the margins set to a maximum of 65 characters across.
With a 65 character line 2 characters on a line should comprise 2/65 of a billable line.
To the best of our knowledge there are no industry standards for calculating lines, and other transcription services may use different methods.
65 character lines for billing are calculated differently than 65 character lines for payroll, which we outline in our METRO TRANSCRIPTION SERVICE BENEFITS MEMO which is available to employees.
