One quick top rope a go and sent the route.

If you carried on straight up from there then you've done Microstorm without a side runner. Chalkstorm goes up the flake which - unless the holds and sequence have changed yet again - is usually reached by moving right and up to the base of the flake several feet below where you are here. Regardless, you seem to be nicely at home on the slab and kudos for running it out.

thanks Michael! appreciate the definitive info on this!

You probably noticed the worn hold just above the overlap in the RH of the blind parallel cracks - originally there was virtually nothing there; and standing on that hold the 3 fingertip "piano playing" holes are probably still there a bit up and right IIRC - originally those holes were pebbles that you pinched. Luckily, the changes like this haven't altered the overall character of the route so it's still as enjoyable.
