In XL 888 crash, the FBW changed law from normal to direct, because landing gear was down. The THS was at max. nose up position in manual mode. The elevator moved accordingly to sidestick input, mostly full ND, but couldn't counter-react the pitch up moment. The FBW switched to alternate for landing gear up. Intersting is the alternate law behaviour with elevator movement in opposition to sidestick input - reference Final report, FDR graph in page 113.
In conclusion, good luck with improving the "manual flying skills" in alternate law.
