That's an acceptable spread for me, unless I'm training with a competive group. You only need close gears to stay at maximum power long enough to close gaps. You are at least as efficeint at 60 RPM as at 90, but you have a lot less power. With a wide gap, sometimes you need to relax and just go a little slower, or put in the effort to stay in a gear that's a little higher than you want. It doesn't make much difference in your time to your destination. IME my commuting times were at least as fast with a single speed as with my race bike, mostly because when I had a lot of gears I always ended up in one of the low ones. YMMV
