Interesting to note how carried-over transfers are working with two races simultaneously. I was carrying forward one transfer on the Giro. However, with both windows open, it shows 3 available for ToC, and 2 for Giro. presumably if I only use 2 at ToC, the Giro one will update to 3 once the ToC window closes.
It does open up an interesting possibility during overlapping races of doing one race as a purist, and getting double the transfers in the other one!
