Reduced weekly rest

Hi all, sorry to be a pain but I’m just about to do a second reduced rest on the bounce, and wanted to check all is legal.

I had 126 hrs rest over Easter thurs to Monday
Then 53 hrs 54 min break following weekend
54 hrs 29 the next weekend
Last weekend I had 40 hrs 33
I’m running in tomorrow (unplanned) and will start again 0400 Monday as of yet don’t know how Long but less than 45 more than 24.

So am I right in thinking I only need 45 hrs next weekend (which is bank holiday) so could again work Saturday leaving 45+ hrs for rest sat afternoon to tues

Thanks Daz
