In-built optimize makes the RMSE(bins) 7% (6% now that I checked again).
The parameters I got from the link which takes more time brings it down to 2.95%
parameters:
0.0600, 0.3690, 3.4252, 7.3442, 7.4576, 0.1680, 1.2247, 0.0586, 1.4001, 0.0171, 0.9224, 1.8133, 0.2455, 0.2576, 2.2416, 0.6477, 3.8554, 0.9509, 0.9145
However, the minimum recommended retention for 3650 days is 0.87 even though in the old version with FSRS 4.5, it was 0.75.
