I was referring to time standing behind the patient, not charting, etc. That's the 5-10 min part. I prep quickly and while it's drying I get everything else ready. Than local and I give it a minute to work while I pull out the catheter and confirm good pt position. LOR, catheter, test, tape. I than go over and start the chart. Quick check for evidence of spinal a few min later and than bolus over a few minutes in aliquots while charting. Hook up PCEA and a quick explanation while they're repositioning her. Out the door. Get a cup of tea and check the vitals again in a few more minutes. I don't check a level. If it doesn't set up, they'll call before long and I tell the pt to not use the PCEA until it sets up. We don't do high risk women, so the likelihood of crashing back is more infrequent. We also have no trainee OBs so no hemming and hawing over the strips and overreacting, with the running and the screaming.

I also don't like to move the needle during a contraction if they're really hurting, so sometimes that adds another minute while I wait to start or reposition the needle.
You'll get faster with experience, but 10 minutes door to door is probably impossible and evidence of poor consent, charting, or monitoring. There's no avoiding that and each step takes a few minutes. Even if they already have a signed consent, I still cover the key R/B/A, and note the discussion. If you were working with a CRNA and only needle jockeying, you could probably be door to door in 5 minutes.
😉 I've never seen that type of practice.
