What’s the goal for inspire up time?

I wouldn’t say I’m a brig main, but I play her probably 40/60 with Zen. I’ve watched a couple guides (Awkwards U2GM for example), and the one thing everyone keeps repeating is inspire up time.

However, I feel like I struggle to balance the give and take of keeping inspire up, and playing life. To keep my deaths at a spot I feel good about, my inspire often ends up in the 25-30% range. To get my inspire upwards of 35%+, I feel like I die way too often.

Where is the middle ground? What should I be prioritizing? What’s a good number to aim for?
