Roblox developer console working differently on the Roblox client

Context: I am using single script architecture, and I am viewing the rate of the framework starter on the server side

Whenever I spam place blocks in my game, of course, the rate increases [In studio, IMAGE 1]. As you see, the rate calms down in the second screenshot after I stop spam clicking.

In studio

In game

First of all, why would doing the exact same action raise the rate of the script by a lot more than in studio? Second of all, does the developer console just randomly freeze sometimes, or is the rate of the script actually stuck at 1283 times per second? :IsStudio is not used in relation to this issue at all in the game, and I am a little baffled.

Note: the rate is higher in [In game, IMAGE 2] since i spam clicked a little bit more after [In game, IMAGE 1].

If anybody could help, please let me know.
