Definitely no. Effects aren't meant to be something every ship has all of.
I'd say that instead of 2.5%, 5%, and 10% for various effects right now, 0.5%, 2.5%, and 5% would be better.
I'd say effect strength is 100% if a system has x% of the reserved-for-modules% on a ship.
Most effects are 100% if they are 50% of that %.
Some coop better with more other effects.
We have 10 effects with an average of 7.5% required? (guessed) -> all maxed out would be 75% with huge power demands (doom, do I have to say cube or sphere?).
If 16% of a ship is reserved for systems, 4% for modules (on a RP server) A current 7.5% module would be maxed out if it has 50% of 4% which is 2% of a ship, while a current 10% module would be maxed out at about 2.33% of a ship.
