Timing to make cheats

Seriously!

it depends on the game and also cheat a lot, so there is no time you can easily say per cheat or game

so let me give you a few examples:

• if you only want to create a money cheat and the game has clean and good development using e.g. a "GetMoney"-function all the time (so the user don't need to enter a menu first), the cheat could be created in a few minutes (also with testing and adding everything to our system it wouldn't need much time)
• if the game has a bad development and thus already don't start on some of our computers, it would need additional time to test and schedule it again which quickly could delay the work by weeks
• if the game uses bad engine for us (e.g. one which is reading all values with a single "GetValue"-function which is reading also the screen resolution together with the money), it would also need much more time from hours to days to create a stable and clean cheat (and sometimes it's also not possible and we've to cancel the work after a lot of hours)
• if the game uses encryption and/or anticheat protections, it could also need much more time from minutes up to days or weeks
• if you like to create a stealth/invisible cheat, there are normally around 4-5 different ways depending on the game and each of them needs multiple hours, but you don't know which one or also if any of them will work at the end... so this also can quickly waste a lot of time

and last but not least: if the schedules trainer maker get's ill, it may happens that there are more new games with higher priority (e.g. due to requests and/or SteamDB) when he is back and the older game has to be queued
