I've had a sportsman. I ran one for years. If I found one for $300 or less I'd.probably have one again.
Mine did have the hatcher set up in the bottom and I ran it like you're doing.
I've also used Hovabators for years. There's been many years I've ran several and nothing else.
I've always had better hatch rates in the hovabators then anything else. Don't get me wrong I love sportsmanship.
They're a good incubator but I've found that they don't hold the same temp throughout. That's kinda the nature of the best with anything bigger.
My incubator holds better temps and more evenly then a sportsman does or I wouldn't have quit working on it and started using it.
I run my hatches similar. I collect and hold my eggs in 30 egg plastic flats and set every 6 days ideally. I turn them when I can. I try to three times a day every 8 hours but sometimes I end up only doing it once or twice a day. I also don't worry about the temp when they're waiting to go in. Some times its lower then ideal but more often and more then they should be they're setting in temps higher then ideal. That's what I mean by me not handling them correctly.
I set every 6 days and move to hatchers on day 18. I use Hovabators because they work for me. Nothing hatches in the incubator so I don't have to clean it. It is literally just add water and add or remove eggs.
I hatch several different projects at the same time so I need different projects to hatch separate so chicks don't get mixed. The way I use separate hatchers and more then one it makes that easier for me to keep things separate and to keep track.
Each cycle is 6 days so that gives me 6 days for lockdown, hatch and cleaning. With the separate hatchers I empty it after hatch and then leave the plastic water tray and the plastic wire floor with dividers soaking for hours or a day in the same tub I use to move chicks to brooders. The yellow tub

I like my set up and how it flows.
