Whoops - it took me a while to spot the clues about edge size and gauges. I put down the wrong units for some of them (I did say I wasn’t an engineer!). Sorry, I think you all spotted it.
They should be:
Edge: 37 mm
Spine: 60 mm
Toe: 14-33 mm
Shoulders: 12 mm
Sweet spot (estimated): 8-23 cm from toe
I haven’t quite been able to get my head round those Algobats either. I don’t doubt that the algorithm is doing what it’s supposed to, but the parameter it’s aiming for isn’t necessarily going to mean that a bat is good or not. I think they do mention other studies and what they’ve looked at. I guess if there were 3D scans of good bats, then they could be analysed in the same way to see how they compare. Surely that’s been done?!
But back to this bat. I actually ended up taking less out above the swell than the templates suggest - in that photo they’re not actually reaching the face yet. In the original design the concaving would go below the edge level! Instead I left a lot more spine all the way to the handle than in the design in the paper. If not, it would have been too heavy, so I took more out near the toe, to raise the middle a bit (it’s still a little low for my liking) and improve pick up. The next bat I’d like to make a version of is the one in the diagram
@DorsetDan posted, with the spine scoop above the swell. But with a higher middle probably.
