Resting Heart Rate and 7 day steps not accurate on Blaze vs Charge HR

[ger2016]

I was using the Charge HR since October and recently upgraded to a Blaze. Since switching a week ago my resting heart rate is higher and ive actually been more active this week with tons of cardio. In addition my 7 day step count is completely off with friends and i have not manually inputted anything. i calculate i should have a running total of over 110,000 and it displays as 93,000. im very active and purchased this model for increased accuracy and ive been very disappointed. also why are there seperate elliptical and spinning modes if it still doesnt accurately calculate steps or distance? seems like it is just for show. i do on a positive note enjoy the running feature but not enough to justify keeping it when other trackers have more features for the same amount of money. Fitbit, how do you explain all these differences?

I've found each time I increase my activity level to a significant degree, my RHR bumps up a bit for a week or two before it either A) levels off back where it started, or B) drops below the baseline of a few weeks prior.

in this case my resting heart rate is showing significantly higher since i switched between the 2 models so i believe this is a glitch or else the Charge was inaccurate.

What do you call significant?

FWIW, I've seen more than ten beats per minute difference in a matter of only a month.

5 beats per minute within less than 12 hours of switching from a Charge HR to a Blaze. Appreciate your reply Shipo but I'm pretty educated on heart rates and looking for an explanation from Fitbit as to why my stats are different when all I did was switch models and nothing else.
