From D&D perspective the whole discussion doesn't make much sense. Your DM will not tell you DC. They will ask for a roll and let you know if you succeeded or failed. They might reveal it from time to time for some drama when DC is 25 or higher.
From video game's player perspective spending several seconds on the same screen hundreds of times? Probably not either. It might look cool the first few times you do it.
