Our SOP is if a deviation irritates the other guy he may well have CRM issues - in which case ask him on the ground "what's the problem".
I suppose there is more than one way to skin a cat, if your calling speed at Vref with a increasing speed trend arrow you have to ask yourself was it a good call. If in doubt - call it!!! then talk about it later. No biggy!!!!
As for calls, I think a call of "Speed" would suffice. At hearing it, your natural reaction is to check your speed anyway, so any call regarding speed is going to attract your scan towards the ASI, why complicate things at a very busy segment with trying to be smart with + or - speed trends. Could easily be misinterpretated as a wrong call ie "outside tolerance" the PF increases thrust instead of reducing excacerbating the problem!!!
Keep it simple, use SOP's and good airmanship (ie SCAN) and everything will be just fine....honest gov
