Different contests, different lineups
Double Ups and 50/50s pay a bit under half the field, and a head-to-head pays one of two, so you want the lineup most likely to clear the line: high floor, low risk. Tournaments pay roughly the top fifth of the field with most of the money at the very top, so you want ceiling and some separation from the field. Each contest in your file gets a suggested build style, and nothing builds until you pick one.
One switch for your choices
Set locks, exclusions and exposures once for every contest in the file, or flip the switch and set GPP and Double Up choices separately. With All contests in file, choose each contest's strategy, review each set of lineups, and build one upload file.
Questions
What's the difference between a GPP and a cash game?
A GPP (tournament) pays roughly the top fifth of the field, with most of the money at the very top. Cash games like Double Ups and 50/50s pay a bit under half the field a flat prize.
Can I build both from one upload?
Yes. Contests come from your entries file, and each gets its own build style and lineups.
Can I use different locks for GPP and cash?
Yes. Keep one set of choices for every contest, or set GPP and Double Up choices separately.
