The cap is a 25% cap on cost, because when you take channeled abilities, efficiency above 175% still counts towards efficiency if you have lower than 100% duration.

Test it out with 190% efficiency (it'll still show 175% in the arsenal) and 40% duration, you'll still get the 25% total cost even though your efficiency is above 175%.
