More cardio on less days or less cardio on more days?

What do you find gives you better results (for whatever goal you're shooting for)?

Right now I'm cutting so I'm supplementing my deficit with added cardio. I try to do 150-180 minutes per week of moderate intensity cardio, usually biking outside. Usually that's been in the form of 75-90 minutes on Saturday and Sunday each. But lately I started doing it during the week before/after my lifting sessions on the gym's stationary bikes since my bike's had some maintenance issues and it's starting to get colder outside. So still the same amount per week, but spread out more throughout the week (30 minutes a day 5 or 6 days).

What prompted me to post this is that I've been losing weight faster this week (the first since I switched to this routine) but it could be for a whole lot of other reasons, so I'll need to keep up this routine for longer to determine if that has anything to do with it.
